6 kitchen mistakes you don’t know you're making

<p>The kitchen is the heart of the home, but it can also be an area where we make the most mistakes in the way we use it. Check out our top tips to help keep your kitchen ship-shape.</p> <p><strong>Clean the inside of the dishwasher</strong></p> <p>You may not realise that the appliance that keeps everything clean can in fact be quite dirty. The inside of the dishwasher can be a breeding ground for bacteria. Run a hot cycle with nothing but a cup of white vinegar in the top and bottom shelves. Then simply wipe clean the sides and seams of the dishwasher.</p> <p><strong>Don’t wash your chicken</strong></p> <p>You may think this is necessary, but in fact washing your chicken can spread bacteria across your work surface, towels, cloths, and your hands. You can avoid it altogether as cooking will get rid of anything harmful on your meat.</p> <p><strong>Change your kitchen towel</strong></p> <p>The towel can be harbouring many kinds of bacteria, so it’s best to change them daily. Don’t rely on the sniff test to see if it needs a wash. A dirty towel used to dry your clean dishes can quickly spread germs that can make you sick.</p> <p><strong>Avoid putting wooden items in the dishwasher</strong></p> <p>The heat from the appliance can cause wooden items to warp and crack. That means wooden chopping boards, salad servers, or pots and pans with wooden handles need to be hand washed.</p> <p><strong>Never wipe up floor spills with the dishcloth or tea towel</strong></p> <p>If you wipe up some spilled milk off the floor and then use that same cloth to wipe your bench, germs can quickly spread. Same goes with a tea towel. Always use paper towel for cleaning mess from the floor.</p> <p><strong>Fix leaking taps</strong></p> <p>It’s too easy to ignore the drip drip of a leaky tap. But did you know a leaking tap could use over 6,000L of water in a month? Save the Earth (and reduce your water bill) by staying on top of any leaks around the home.</p> <p><strong>Have a separate chopping board for meat</strong></p> <p>Cross contamination can occur if you chop raw meat on a chopping board and then use it later (even after cleaning) for chopping fruit or vegetables. It’s best to have a board designated just for meat – it’s great if it’s a different colour to your everyday boards. Wash in hot soapy water after each use.</p> <p><em>Image credits: Getty Images </em></p>

Good news: midlife health is about more than a waist measurement. Here’s why

<p><em><a href="https://theconversation.com/profiles/rob-newton-12124">Rob Newton</a>, <a href="https://theconversation.com/institutions/edith-cowan-university-720">Edith Cowan University</a></em></p> <p>You’re not in your 20s or 30s anymore and you know regular health checks are important. So you go to your GP. During the appointment they measure your waist. They might also check your weight. Looking concerned, they recommend some lifestyle changes.</p> <p>GPs and health professionals commonly <a href="https://theconversation.com/the-body-mass-index-cant-tell-us-if-were-healthy-heres-what-we-should-use-instead-211190">measure waist circumference</a> as a vital sign for health. This is a better indicator than body mass index (BMI) of the amount of intra-abdominal fat. This is the really risky fat around and within the organs that can drive heart disease and metabolic disorders such as type 2 diabetes.</p> <p>Men are at greatly increased risk of health issues if their waist circumference is <a href="https://www.bmj.com/content/311/7017/1401">greater than 102 centimetres</a>. Women are considered to be at greater risk with a waist circumference of <a href="https://www.bmj.com/content/311/7017/1401">88 centimetres or more</a>. More than <a href="https://www.abs.gov.au/statistics/health/health-conditions-and-risks/waist-circumference-and-bmi/latest-release">two-thirds of Australian adults</a> have waist measurements that put them at an increased risk of disease. An even better indicator is waist circumference divided by height or <a href="https://www.baker.edu.au/news/in-the-media/waist-height-ratio#:%7E:text=According%20to%20research%2C%20a%20healthy,the%20highest%20risk%20of%20disease.">waist-to-height ratio</a>.</p> <p>But we know people (especially women) have a propensity to <a href="https://www.ajog.org/article/S0002-9378(19)30588-5/abstract">gain weight around their middle during midlife</a>, which can be very hard to control. Are they doomed to ill health? It turns out that, although such measurements are important, they are not the whole story when it comes to your risk of disease and death.</p> <h2>How much is too much?</h2> <p>Having a waist circumference to height ratio larger than 0.5 is associated with greater risk of chronic disease as well as premature death and this applies in adults of any age. A healthy waist-to-height ratio is between 0.4 to 0.49. A ratio of 0.6 or more <a href="https://www.baker.edu.au/news/in-the-media/waist-height-ratio#:%7E:text=According%20to%20research%2C%20a%20healthy,the%20highest%20risk%20of%20disease">places a person at the highest risk of disease</a>.</p> <p>Some experts recommend <a href="https://www.nature.com/articles/s41574-019-0310-7">waist circumference be routinely measured in patients during health appointments</a>. This can kick off a discussion about their risk of chronic diseases and how they might address this.</p> <p>Excessive body fat and the associated health problems manifest more strongly during midlife. A range of social, personal and physiological factors come together to make it more difficult to control waist circumference as we age. Metabolism tends to slow down mainly due to decreasing muscle mass because people do <a href="https://onlinelibrary.wiley.com/doi/10.1002/jcb.25077">less vigorous physical activity, in particular resistance exercise</a>.</p> <p>For women, hormone levels begin changing in mid-life and this also <a href="https://www.tandfonline.com/doi/full/10.3109/13697137.2012.707385">stimulates increased fat levels particularly around the abdomen</a>. At the same time, this life phase (often involving job responsibilities, parenting and caring for ageing parents) is when elevated stress can lead to <a href="https://journals.lww.com/psychosomaticmedicine/abstract/2000/09000/stress_and_body_shape__stress_induced_cortisol.5.aspx">increased cortisol which causes fat gain in the abdominal region</a>.</p> <p>Midlife can also bring poorer sleep patterns. These contribute to fat gain with <a href="https://journals.plos.org/plosmedicine/article?id=10.1371/journal.pmed.0010062">disruption to the hormones that control appetite</a>.</p> <p>Finally, your family history and genetics can <a href="https://journals.plos.org/plosgenetics/article?id=10.1371/journal.pgen.1002695">make you predisposed to gaining more abdominal fat</a>.</p> <h2>Why the waist?</h2> <p>This intra-abdominal or visceral fat is much more metabolically active (it has a greater impact on body organs and systems) than the fat under the skin (subcutaneous fat).</p> <p>Visceral fat surrounds and infiltrates major organs such as the liver, pancreas and intestines, releasing a variety of chemicals (hormones, inflammatory signals, and fatty acids). These affect inflammation, lipid metabolism, cholesterol levels and insulin resistance, <a href="https://academic.oup.com/eurheartjsupp/article/8/suppl_B/B4/461962">contributing to the development of chronic illnesses</a>.</p> <p>The issue is particularly evident <a href="https://www.ajog.org/article/S0002-9378(19)30588-5/abstract">during menopause</a>. In addition to the direct effects of hormone changes, <a href="https://www.sciencedirect.com/science/article/pii/S0960076013001118?via%3Dihub">declining levels of oestrogen change brain function, mood and motivation</a>. These psychological alterations can result in reduced physical activity and increased eating – often of comfort foods high in sugar and fat.</p> <p>But these outcomes are not inevitable. Diet, exercise and managing mental health can limit visceral fat gains in mid-life. And importantly, the waist circumference (and ratio to height) is just one measure of human health. There are so many other aspects of body composition, exercise and diet. These can have much larger influence on a person’s health.</p> <h2>Muscle matters</h2> <p>The quantity and quality of skeletal muscle (attached to bones to produce movement) a person has makes a <a href="https://www.nature.com/articles/nrendo.2012.49">big difference</a> to their heart, lung, metabolic, immune, neurological and mental health as well as their physical function.</p> <p>On current evidence, it is equally or more important for health and longevity to <a href="https://www.bmj.com/content/345/bmj.e7279">have</a> higher muscle mass and better cardiorespiratory (aerobic) fitness than waist circumference within the healthy range.</p> <p>So, if a person does have an excessive waist circumference, but they are also sedentary and have less muscle mass and aerobic fitness, then the recommendation would be to focus on an appropriate exercise program. The fitness deficits should be addressed as priority rather than worry about fat loss.</p> <p>Conversely, a person with low visceral fat levels is not necessarily fit and healthy and may have quite poor aerobic fitness, muscle mass, and strength. <a href="https://bjsm.bmj.com/content/45/6/504">The research evidence</a> is that these vital signs of health – how strong a person is, the quality of their diet and how well their heart, circulation and lungs are working – are more predictive of risk of disease and death than how thin or fat a person is.</p> <p>For example, a <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5510687/">2017 Dutch study</a> followed overweight and obese people for 15 years and found people who were very physically active had no increased heart disease risk than “normal weight” participants.</p> <h2>Getting moving is important advice</h2> <p>Physical activity has many benefits. Exercise can counter a lot of the negative behavioural and physiological changes that are occurring during midlife including for people going through menopause.</p> <p>And regular exercise reduces the tendency to use food and drink to help manage what can be a <a href="https://journals.lww.com/acsm-msse/fulltext/2008/05000/physical_activity,_sedentary_index,_and_mental.7.aspx">quite difficult time in life</a>.</p> <p>Measuring your waist circumference and monitoring your weight remains important. If the measures exceed the values listed above, then it is certainly a good idea to make some changes. Exercise is effective for fat loss and in particular <a href="https://bjsm.bmj.com/content/57/16/1035">decreasing visceral fat</a> with greater effectiveness when <a href="https://bmcwomenshealth.biomedcentral.com/articles/10.1186/s12905-019-0864-5">combined with dietary restriction of energy intake</a>. Importantly, any fat loss program – whether through drugs, diet or surgery – is also a muscle loss program unless resistance exercise is part of the program. Talking about your overall health with a doctor is a great place to start.</p> <p><a href="https://www.essa.org.au/Public/Public/Searches/find-aep-withdistance.aspx">Accredited exercise physiologists</a> and <a href="https://member.dietitiansaustralia.org.au/Portal/Portal/Search-Directories/Find-a-Dietitian.aspx">accredited practising dietitians</a> are the most appropriate allied health professionals to assess your physical structure, fitness and diet and work with you to get a plan in place to improve your health, fitness and reduce your current and future health risks.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/226019/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/rob-newton-12124"><em>Rob Newton</em></a><em>, Professor of Exercise Medicine, <a href="https://theconversation.com/institutions/edith-cowan-university-720">Edith Cowan University</a></em></p> <p><em>Image credits: Getty Images</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Everything you need to know before you travel to Vietnam

<p dir="ltr">So you’ve booked your flight to Vietnam to experience the best of south-east Asia. </p> <p dir="ltr">When travelling to Vietnam, and other Asian countries, there are a handful of tips and tricks to be aware of to ensure you have a smooth sailing travel experience. </p> <p dir="ltr">In comparison to travelling around Western countries, exploring Vietnam comes with a unique set of circumstances, and being prepared for every situation will make sure your trip is one to remember. </p> <p dir="ltr"><strong>Cash is king</strong></p> <p dir="ltr">When it comes to planning your trip to Vietnam, other than booking your flights, hotels and travel insurance, one of your first priorities should be getting your hands on cash. </p> <p dir="ltr">The Vietnamese Dong is a unique currency to get used to, given that $5 AUD is equal to approximately $82,000 VND. </p> <p dir="ltr">Most of the restaurants, cafes and tourist attractions you’ll be heading to will only accept cash, so make sure you seek out an ATM (most ATMs will let you translate to English) and always have a decent amount of cash on hand. </p> <p dir="ltr"><strong>Go off the beaten track </strong></p> <p dir="ltr">Vietnam has so much more to offer than the major cities. </p> <p dir="ltr">While Hanoi and Ho Chi Minh City have a lot of interesting history, tourist attractions and unique cultural experiences, staying in these cities for the entirety of your Vietnam trip is limiting. </p> <p dir="ltr">Make sure you explore coastal towns such as Hoi An, Hue and Phu Quoc, explore the rolling rice fields of Sapa, and don’t forget to book your cruise around the picturesque Ha Long Bay. </p> <p dir="ltr"><strong>Don't be afraid of the food </strong></p> <p dir="ltr">While Vietnamese food is maybe not what you’re used to eating everyday, part of experiencing a different culture is immersing yourself in the food scene. </p> <p dir="ltr">One of the best things you can do when you arrive at your destination is to book a food tour with a local guide (there are many available through TripAdvisor), to take you around and show you a variety of dishes to become accustomed to. </p> <p dir="ltr">Your food tour guide will also help ease your anxiety over ordering food in different places. </p> <p dir="ltr">Another top tip: Restaurants will often be called the name of the dishes they serve. For example, places that sell the delicious Bahn Mi bread rolls will have “Bahn Mi” in their name. </p> <p dir="ltr"><strong>Google Translate is your friend </strong></p> <p dir="ltr">While your hotel staff will often speak good English, other vendors at restaurants or markets may not be as fluent. </p> <p dir="ltr">Downloading the Google Translate app on your phone will allow you to communicate with locals quickly and easily, by typing in what you want to say in English, and letting the app read out the sentence in Vietnamese. </p> <p dir="ltr">Also, the app’s camera feature lets you hover your smartphone camera over something written in Vietnamese, before translating it into English in seconds. </p> <p dir="ltr"><strong>Beware of scams</strong> </p> <p dir="ltr">One of the most common scams in Vietnam is taxi scams. Some people will claim to be a taxi and then jack up the prices once they take you to your destination. </p> <p dir="ltr">To avoid this, only get in registered taxis (that actually look like taxis and not just a random car), and download Grab, which is the Vietnamese version of Uber and is just as easy to use. </p> <p dir="ltr">Another common scam is for market vendors to hike up prices for food and souvenirs, so be ready to barter for a better price. </p> <p dir="ltr"><strong>Make friends with the locals </strong></p> <p dir="ltr">The Vietnamese people are some of the loveliest, kindest and most accommodating in the world. </p> <p dir="ltr">People on the street, hotel staff and restaurant workers are always happy to help you with queries or concerns, so make the most of their local knowledge and don’t be afraid to approach people with a smile. </p> <p dir="ltr"><em>Image credits: Getty Images </em></p>

Silent cancers: here’s what you need to know when there are no obvious symptoms

<p><em><a href="https://theconversation.com/profiles/justin-stebbing-1405462">Justin Stebbing</a>, <a href="https://theconversation.com/institutions/anglia-ruskin-university-1887">Anglia Ruskin University</a></em></p> <p>The recent revelations about the Princess of Wales’s <a href="https://www.bbc.com/news/uk-68640917">cancer diagnosis</a> highlight a crucial aspect of cancer detection – the disease’s sometimes silent nature.</p> <p>Silent cancers are those without noticeable symptoms. They pose a unique challenge in early detection and treatment.</p> <p>Contrary to common perception, cancer does not always announce its presence through overt symptoms or obvious signs. Many people receive a <a href="https://academic.oup.com/clinchem/article-abstract/70/1/179/7283928">cancer diagnosis incidentally</a>, when it’s found during routine medical examinations or investigations for unrelated health concerns – as seems to be the case for both <a href="https://www.wsj.com/health/kate-middleton-catherine-cancer-what-is-preventative-chemotherapy-9625370d">the princess</a> and <a href="https://www.bbc.co.uk/news/health-68171163">King Charles III</a>.</p> <p>While even silent cancers can sometimes be <a href="https://pubmed.ncbi.nlm.nih.gov/22584215/">aggressive and advance rapidly</a>, they can also remain <a href="https://pubmed.ncbi.nlm.nih.gov/20363069/">dormant</a> for years or <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8819710/">even decades</a>. Some <a href="https://ascopubs.org/doi/10.14694/EdBook_AM.2012.32.98">prostate</a>, <a href="https://ascopubs.org/doi/10.14694/EdBook_AM.2012.32.301">breast</a> and <a href="https://www.frontiersin.org/journals/endocrinology/articles/10.3389/fendo.2020.571421/full">thyroid</a> cancers, for example, <a href="https://www.tmlep.com/clinical-learning/2023-01-23-when-did-this-tumour-start-the-need-for-a-gompertzian-understanding-of-tumour-growth-kinetics">often evolve slowly</a> without obvious symptoms or spreading beyond the original area.</p> <p>Research suggests that some of these cancers are <a href="https://www.frontiersin.org/journals/endocrinology/articles/10.3389/fendo.2020.571421/full">overtreated</a>. Sometimes patients are best left alone or treated much more gently, perhaps even without medical intervention, using a <a href="https://www.nejm.org/doi/full/10.1056/nejmoa1311593">“watch and wait”</a> strategy. This approach may be taken with prostate cancer in the elderly, for example.</p> <h2>The importance of early diagnosis</h2> <p>Whatever the cancer, it’s always important to get an early diagnosis though – and for silent cancers, this is obviously a challenge.</p> <p>Some cancer symptoms <a href="https://pubmed.ncbi.nlm.nih.gov/36702593/">can be vague</a> and easily mistaken for benign ailments. Fatigue, unexplained weight loss and persistent pain are among the nonspecific symptoms that may signal an underlying malignancy. But such symptoms can be misinterpreted or easily dismissed, which contributes to delayed diagnosis and treatment.</p> <figure><iframe src="https://www.youtube.com/embed/MGMy6BzBvp0?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <p>Fortunately, in many countries including the UK, we have <a href="https://www.england.nhs.uk/cancer/early-diagnosis/screening-and-earlier-diagnosis/">screening</a> tests for diseases like breast or colon cancer, to increase early diagnoses.</p> <p>Early diagnosis is a <a href="https://acsjournals.onlinelibrary.wiley.com/doi/full/10.1002/cncr.32887">key factor</a> for successful cancer treatment. Detecting cancer in its silent phase offers a window of opportunity for early intervention and improved outcomes. The discovery of asymptomatic cancers through diagnostic imaging or screening tests underscores the importance of these proactive healthcare measures.</p> <p>Identifying cancer at an early stage means the disease is confined to its site of origin, smaller and potentially easier to cure. Diagnosing a smaller cancer often means that if an operation is needed, it may be a less invasive surgery. There may also be a <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6825992/">lower chance</a> of needing post-operative preventative chemotherapy, to mop up any residual cells.</p> <p>Colorectal cancer (CRC) is a good example to show the critical importance of screening. Studies show that patients who participate in CRC <a href="https://www.nice.org.uk/guidance/dg56/chapter/1-Recommendations">screening</a>, such as colonoscopies or tests that look for blood in the stool, are more likely to be diagnosed while asymptomatic and have more positive prognoses after treatment. Those diagnosed with CRC after showing symptoms, such as rectal bleeding or changes in bowel habits, tend to have more <a href="https://bmjopengastro.bmj.com/content/4/1/e000146%20">advanced tumors and poorer outcomes</a>.</p> <figure><iframe src="https://www.youtube.com/embed/nA9_Io3LDpA?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <p>Public health initiatives aimed at raising awareness about the importance of both cancer screening and symptom recognition play a pivotal role in reducing diagnostic delays. Empowering people to engage in <a href="https://healthcaredelivery.cancer.gov/prevention/#:%7E:text=Cancer%20can%20be%20prevented%20through,they%20are%20more%20easily%20treated.">preventive healthcare measures</a> such as HPV vaccinations and lifestyle changes that decrease risk can facilitate early detection and intervention, potentially altering the trajectory of the disease.</p> <h2>Biomarker discovery</h2> <p>The latest advances in diagnostic technologies, often known as <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8012218/#:%7E:text=During%20biomarker%20discovery%2C%20evaluation%20of,design%20of%20future%20validation%20studies.">“biomarker discovery”</a>, hold promise for improving early detection rates and refining treatment strategies for silent cancers. From <a href="https://www.cancer.gov/publications/dictionaries/cancer-terms/def/molecular-profiling">molecular profiling</a> to <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9922467/">liquid biopsy techniques</a> (blood tests to diagnose cancer), innovative approaches are reshaping the landscape of cancer diagnosis, offering new avenues for personalised and precision medicine.</p> <p>For example, I worked with a team using blood tests to identify cancers in more than <a href="https://www.nature.com/articles/s41388-023-02591-z">1,000 women recalled after screening for mammography</a>. We looked at the DNA that tumour cells release – so-called <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10496721/">cell-free DNA</a> – and also metabolomics (rare markers related to metabolism in the blood). From this information, we found healthy patients, benign disease, pre-cancer and breast cancer. Although there’s increasing awareness and use of this <a href="https://www.sciencedirect.com/science/article/abs/pii/S1769721218307110">approach in Europe</a>, it isn’t standard in the UK.</p> <p>Asymptomatic cancers represent a formidable challenge for patient care. But, by encouraging patients to adopt preventive lifestyles and engage with screenings and tests, asymptomatic cancers don’t have to be a hidden threat to health.<!-- Below is The Conversation's page counter tag.

Eating some chocolate really might be good for you – here’s what the research says

<p><em><a href="https://theconversation.com/profiles/dan-baumgardt-1451396">Dan Baumgardt</a>, <a href="https://theconversation.com/institutions/university-of-bristol-1211">University of Bristol</a></em></p> <p>Although it always makes me scoff slightly to see Easter eggs making their first appearance in supermarkets at the end of December, there are few people who aren’t delighted to receive a bit of chocolate every year.</p> <p>It makes sense that too much chocolate would be bad for you because of the high fat and sugar content in most products. But what should we make of common claims that eating some chocolate is actually good for you?</p> <p>Happily, there is a fair amount of evidence that shows, in the right circumstances, chocolate may be both beneficial for your heart and good for your mental state.</p> <p>In fact, chocolate – or more specifically cacao, the raw, unrefined bean – is a medicinal wonder. It contains many different active compounds which can evoke pharmacological effects within the body, like medicines or drugs.</p> <p>Compounds that lead to neurological effects in the brain have to be able to cross the <a href="https://link.springer.com/chapter/10.1007/978-3-642-13443-2_7">blood-brain barrier</a>, the protective shield which prevents harmful substances – like toxins and bacteria – entering the delicate nervous tissue.</p> <p>One of these is the compound <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3672386/">theobromine</a>, which is also found in tea and contributes towards its bitter taste. Tea and chocolate also contain caffeine, which theobromine is related to as part of the purine family of chemicals.</p> <p>These chemicals, among others, contribute to chocolate’s addictive nature. They have the ability to cross the blood-brain barrier, where they can influence the nervous system. They are therefore known as <a href="https://pubmed.ncbi.nlm.nih.gov/15549276/">psychoactive</a> chemicals.</p> <figure><iframe src="https://www.youtube.com/embed/HloqayQdR6M?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <p>What effects can chocolate have on mood? Well, <a href="https://academic.oup.com/nutritionreviews/article/71/10/665/1931144?login=false">a systematic review</a> looked at a group of studies which examined the feelings and emotions associated with consuming chocolate. Most demonstrated improvements in mood, anxiety, energy and states of arousal.</p> <p>Some noted the feeling of guilt, which is perhaps something we’ve all felt after one too many Dairy Milks.</p> <h2>Health benefits of cocoa</h2> <p>There are other organs, aside from the brain, that might benefit from the medicinal effects of cocoa. For centuries, chocolate has been used as a medicine to treat a <a href="https://pubmed.ncbi.nlm.nih.gov/10917925/">long list of diseases</a> including anaemia, tuberculosis, gout and even low libido.</p> <p>These might be spurious claims but there is evidence to suggest that eating cacao has a positive effect on the cardiovascular system. First, it can prevent <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8068178/">endothelial dysfunction</a>. This is the process through which arteries harden and get laden down with fatty plaques, which can in turn lead to heart attacks and strokes.</p> <p>Eating dark chocolate may also reduce <a href="https://www.sciencedirect.com/science/article/pii/S1537189115001135?via%3Dihub">blood pressure</a>, which is another risk factor for developing arterial disease, and prevent formation of clots which block up blood vessels.</p> <figure><iframe src="https://www.youtube.com/embed/8VUcPCbSSCY?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <p>Some studies have suggested that dark chocolate might be useful in adjusting ratios of <a href="https://pubmed.ncbi.nlm.nih.gov/20968113/">high-density lipoprotein cholesterol</a>, which can help protect the heart.</p> <p>Others have examined insulin resistance, the phenomenon associated with Type 2 diabetes and weight gain. They suggest that the <a href="https://www.sciencedirect.com/science/article/pii/S0963996900000697#:%7E:text=Cocoa%20is%20rich%20in%20polyphenols%20particularly%20in%20catechins,and%20cocoa%20powder%20have%20been%20published%20only%20recently.">polyphenols</a> – chemical compounds present in plants – found in foodstuffs like chocolate may also lead to <a href="https://pubmed.ncbi.nlm.nih.gov/29993262/">improved control of blood sugars</a>.</p> <h2>Chocolate toxicity</h2> <p>As much as chocolate might be considered a medicine for some, it can be a poison for others.</p> <p>It’s well documented that the ingestion of caffeine and theobromine is highly toxic for domestic animals. Dogs are <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4801869/">particularly affected</a> because of their often voracious appetites and generally unfussy natures.</p> <p>The culprit is often dark chocolate, which can provoke symptoms of agitation, rigid muscles and even seizures. In certain cases, if ingested in high enough quantities, it can lead to comas and abnormal, even fatal heart rhythms.</p> <p>Some of the compounds found in chocolate have also been found to have potentially negative effects in humans. Chocolate is a source of oxalate which, along with calcium, is one of the main components of <a href="https://pubmed.ncbi.nlm.nih.gov/20301742/">kidney stones</a>.</p> <p>Some clinical groups have advised against consuming oxalate rich foods, such as spinach and rhubarb – and chocolate, for those who suffer from recurrent kidney stones.</p> <p>So, what should all this mean for our chocolate consumption habits? Science points in the direction of chocolate that has as high a cocoa solid content as possible, and the minimum of extras. The potentially harmful effects of chocolate are more related to fat and sugar, and may counteract any possible benefits.</p> <p>A daily dose of 20g-30g of plain or dark chocolate with cocoa solids above 70% – rather than milk chocolate, which contains fewer solids and white chocolate, which contains none – could lead to a greater health benefit, as well as a greater high.</p> <p>But whatever chocolate you go for, please don’t share it with the dog.<!-- Below is The Conversation's page counter tag.

Here’s why having chocolate can make you feel great or a bit sick – plus 4 tips for better eating

<p><em><a href="https://theconversation.com/profiles/saman-khalesi-366871">Saman Khalesi</a>, <a href="https://theconversation.com/institutions/cquniversity-australia-2140">CQUniversity Australia</a></em></p> <p>Australians are <a href="https://www.retail.org.au/media/sweet-spending-boon-predicted-for-easter-retail">predicted</a> to spend around A$1.7 billion on chocolates, hot cross buns and other special foods this Easter season.</p> <p>Chocolate has a long history of production and consumption. It is made from cacao beans that go through processes including fermentation, drying, roasting and grounding. What is left is a rich and fatty liquor that is pressed to remove the fat (cocoa butter) and the cacao (or “cocoa”) powder which will then be mixed with different ingredients to produce dark, milk, white and other types of chocolates.</p> <p>There are several health benefits and potential problems that come in these sweet chocolatey packages.</p> <h2>The good news</h2> <p>Cacao beans contain <a href="https://foodstruct.com/food/cocoa-bean">minerals</a> like iron, potassium, magnesium, zinc and phosphorus and some vitamins. They are also rich in beneficial chemicals called <a href="https://pubmed.ncbi.nlm.nih.gov/23150750/">polyphenols</a>.</p> <p>These are great antioxidants, with the potential to <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5465250/">improve heart health</a>, increase <a href="https://pubmed.ncbi.nlm.nih.gov/25164923/">nitric oxide</a> (which dilates blood vessels) and <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3488419/">reduce blood pressure</a>, provide food for gut microbiota and <a href="https://www.mdpi.com/2072-6643/12/7/1908">promote gut health</a>, boost the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5465250/">immune system</a> and reduce inflammation.</p> <p>However, the concentration of polyphenols in the chocolate we eat depends largely on the cocoa solid amounts used in the final product.</p> <p>In general terms, the darker the chocolate, the more cocoa solids, minerals and polyphenols it has. For example, dark chocolates may have around <a href="https://www.tandfonline.com/doi/full/10.1080/10942912.2011.614984">seven times more polyphenols</a> compared to white chocolates and <a href="https://www.tandfonline.com/doi/full/10.1080/10942912.2011.614984">three times more polyphenols</a> compared to milk chocolates.</p> <h2>But also some bad news</h2> <p>Unfortunately, the <a href="https://theconversation.com/treat-or-treatment-chocolate-is-good-but-cocoa-is-better-for-your-heart-3084">health benefits of cocoa solids</a> are easily offset by the high sugar and fat content of modern-day chocolates. For example, milk and white chocolate eggs are on average 50% sugar, 40% fat (mostly saturated fats) – which means a lot of added kilojoules (calories).</p> <p>Also, there may be some side effects that come with ingesting chocolate.</p> <p>Cocoa beans include a compound called theobromine. While it has the anti-inflammatory properties responsible for some of the health benefits of chocolate, it is also a mild brain stimulant that acts in a similar way to caffeine. The mood boost it offers may also be partly responsible for how much we <a href="https://www.frontiersin.org/articles/10.3389/fphar.2015.00030/full?crsi=662496658&amp;cicada_org_src=healthwebmagazine.com&amp;cicada_org_mdm=direct">like chocolate</a>. Dark chocolate has higher theobromine compared to milk and white chocolate.</p> <p>But accordingly, overindulging in chocolate (and therefore theobromine) may lead to feeling restless, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3672386/">headaches</a> and nausea.</p> <h2>What else is in your chocolate?</h2> <p>Milk and dairy-based chocolates may also cause stomach upset, abdominal pain and bloating in people with <a href="https://dietitiansaustralia.org.au/health-advice/lactose-intolerance">lactose intolerance</a>. This happens when we don’t produce enough lactase enzymes to digest milk sugar (lactose).</p> <p>People with lactose intolerance can usually tolerate up to 6 grams of lactose without showing symptoms. Milk chocolate can have around <a href="https://www.ncbi.nlm.nih.gov/books/NBK310258/">3 grams of lactose</a> per 40 grams (the size of a standard chocolate bar). So two chocolate bars (or the equivalent in milk chocolate eggs or bunnies) may be enough to cause symptoms.</p> <p>It’s worth noting that lactase enzyme activity dramatically declines as we age, with the highest activity in newborns and children. So lactose sensitivity or intolerance may not be such an issue for your kids and your symptoms may increase over time. Genetics also plays a major role in how sensitive people are to lactose.</p> <p><a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6815241/">Allergic reactions</a> to chocolate are usually due to the added ingredients or cross-contamination with potential allergens such as nuts, milk, soy, and some sweeteners used in the production of chocolate.</p> <p>Symptoms can be mild (acne, rashes and stomach pain) or more severe (swelling of the throat and tongue and shortness of breath).</p> <p>If you or your family members have known allergic reactions, make sure you read the label before indulging – especially in a whole block or basket of the stuff. And if you or your family members do experience symptoms of an allergic reaction after eating chocolate, <a href="https://www.betterhealth.vic.gov.au/health/conditionsandtreatments/allergic-reactions-emergency-first-aid">seek medical attention</a> immediately.</p> <h2>4 take home tips</h2> <p>So, if you are like me and have a weakness for chocolate there are a few things you can do to make the experience a good one.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/202848/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <ol> <li>keep an eye out for the darker chocolate varieties with higher cocoa solids. You may notice a percentage on labelling, which refers to how much of its weight is from cocoa beans. In general, the higher this percentage, the lower the sugar. White chocolate has almost no cocoa solid, and mostly cocoa butter, sugar and other ingredients. Dark chocolate has 50–100% cocoa beans, and less sugar. Aim for at least 70% cocoa</li> <li>read the fine print for additives and possible cross-contamination, especially if allergies might be an issue</li> <li>the ingredients list and nutrition information panel should tell you all about the chocolate you choosing. Go for varieties with lower sugar and less saturated fat. Nuts, seeds and dried fruits are better ingredients to have in your chocolate than sugar, creme, syrup, and caramel</li> <li>finally, treat yourself – but keep the amount you have within sensible limits!</li> </ol> <p><em><a href="https://theconversation.com/profiles/saman-khalesi-366871">Saman Khalesi</a>, Postdoctoral Fellow of the National Heart Foundation &amp; Senior Lecturer and Discipline Lead in Nutrition, School of Health, Medical and Applied Sciences, <a href="https://theconversation.com/institutions/cquniversity-australia-2140">CQUniversity Australia</a></em></p> <p><em>Image credits: Getty Images</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Should you be concerned about flying on Boeing planes?

<p><em><a href="https://theconversation.com/profiles/doug-drury-1277871">Doug Drury</a>, <a href="https://theconversation.com/institutions/cquniversity-australia-2140">CQUniversity Australia</a></em></p> <p>The American aerospace giant Boeing has been synonymous with safe air travel for decades. Since the 1990s, Boeing and its European competitor Airbus have dominated the market for large passenger jets.</p> <p>But this year, Boeing has been in the news for all the wrong reasons. In January, an emergency door plug <a href="https://www.seattletimes.com/business/boeing-aerospace/alaska-airlines-let-boeing-max-fly-despite-warning-signals">blew off a Boeing 737 MAX</a> in mid flight, triggering an investigation from United States federal regulators.</p> <p>More recently, we have seen a Boeing plane lose a tyre while taking off, another flight turned back as the plane was leaking fluid, an apparent engine fire, a landing gear collapse, a stuck rudder pedal, and a plane “dropping” in flight and <a href="https://theconversation.com/latam-flight-800-just-dropped-in-mid-flight-injuring-dozens-an-expert-explores-what-happened-and-how-to-keep-yourself-safe-225554">injuring dozens of passengers</a>. A Boeing engineer who had raised concerns regarding quality control during the manufacturing process on the company’s 787 and 737 MAX planes also <a href="https://www.bbc.com/news/business-68534703">died earlier this week</a>, apparently of a self-inflicted gunshot wound.</p> <p>As members of the travelling public, should we be concerned? Well, yes and no.</p> <h2>Many problems, but not all can be blamed on Boeing</h2> <p>The recent parade of events has certainly been dramatic – but not all of them can be blamed on Boeing. Five incidents occurred on aircraft owned and operated by United Airlines and were related to factors outside the manufacturer’s control, like maintenance issues, potential foreign object debris, and possible human error.</p> <p>A <a href="https://www.independent.co.uk/travel/news-and-advice/united-airlines-plane-tire-blowout-boeing-b2509241.html">United Airlines 777</a> flying from San Francisco to Japan lost a tyre on takeoff, a maintenance issue not related to Boeing. The aircraft landed safely in Los Angeles.</p> <p>A <a href="https://www.mercurynews.com/2024/03/12/united-airlines-reports-fifth-flight-incident-in-a-week-as-jet-turns-back-due-to-maintenance-issue/">United Airlines flight from Sydney</a> to Los Angeles had to return to Sydney due to a “maintenance issue” after a fluid was seen leaking from the aircraft on departure.</p> <p>A <a href="https://www.nbcnews.com/news/us-news/passenger-video-shows-flames-shoot-united-airlines-engine-midflight-rcna142217">United Airlines 737-900</a> flying from Texas to Florida ended up with some plastic bubble wrap in the engine, causing a suspected <a href="https://skybrary.aero/articles/compressor-stall#:%7E:text=Compressor%20stalls%20cause%20the%20air,dirty%20or%20contaminated%20compressor%20components">compressor stall</a>. This is a disruption of air flow to an operating engine, making it “backfire” and emit flames.</p> <p>A <a href="https://simpleflying.com/united-boeing-737-max-houston-runway-incident/">United Airlines 737 Max</a> flying from Tennessee to Texas suffered a gear collapse after a normal landing. The pilot continued to the end of the runway before exiting onto a taxiway – possibly at too high a speed – and the aircraft ended up in the grass and the left main landing gear collapsed.</p> <p>The fifth event occurred on a <a href="https://www.nbcnews.com/news/us-news/another-boeing-max-mishap-ntsb-probes-stuck-rudder-pedals-united-airli-rcna142286">United Airlines 737-8</a> flight from the Bahamas to New Jersey. The pilots reported that the rudder pedals, which control the left and right movement of the aircraft in flight, were stuck in the neutral position during landing.</p> <h2>Manufacturing quality concerns</h2> <p>The <a href="https://www.seattletimes.com/business/boeing-aerospace/alaska-airlines-let-boeing-max-fly-despite-warning-signals">exit door plug failure in January</a> occurred on an Alaska Airlines flight. US regulators are currently investigating Boeing’s <a href="https://www.vox.com/money/24052245/boeing-corporate-culture-737-airplane-safety-door-plug">manufacturing quality assurance</a> as a result.</p> <p>The door plug was installed by a Boeing subcontractor called Spirit AeroSystem. The door plug bolts were not properly secured and the plug door fell off in flight. The same aircraft had a series of pressurisation alarms on two previous flights, and was scheduled for a maintenance inspection at the completion of the flight.</p> <p>Spirit got its start after Boeing shut down its own manufacturing operations in Kansas and Oklahoma, and Boeing is now in the process of <a href="https://www.cnbc.com/2024/03/01/spirit-aerosystems-boeing.html">buying the company</a> to improve quality oversight. Spirit currently works with Airbus, as well, though that may change.</p> <h2>What changed at Boeing</h2> <p>Critics say the <a href="https://www.washingtonpost.com/business/2024/03/12/boeing-whistleblower-death-plane-issues/">culture at Boeing has changed</a> since Airbus became a major competitor in the early 2000s. The company has been accused of shifting its focus to profit at the expense of quality engineering.</p> <p>Former staff have raised concerns over tight production schedules, which increased the pressure on employees to finish the aircraft. This caused many engineers to question the process, and the US Federal Aviation Administration (FAA) to fine Boeing for lapses in quality oversight after tools and debris were found on aircraft being inspected.</p> <p>Several employees have testified before US Congress on the production issues regarding quality control. Based on the congressional findings, the FAA began to inspect Boeing’s processes more closely.</p> <p>Several Boeing employees noted there was a high staff turnover rate during the COVID pandemic. This is not unique to Boeing, as all manufacturing processes and airline maintenance facilities around the globe were also hit with high turnover.</p> <p>As a result, there is an acute shortage of qualified maintenance engineers, as well as pilots. These shortages have created several issues with the airline industry successfully returning to the <a href="https://www.aviationbusinessnews.com/mro/critical-shortage-of-engineers-means-looming-crisis-for-aviation-warns-aeroprofessional/">pre-pandemic levels</a> of 2019. Airlines and maintenance training centres around the globe are working hard to train replacements, but this takes time as one cannot become a qualified engineer or airline pilot overnight.</p> <p>So, is it still safe to fly on Boeing planes? Yes it is. Despite dramatic incidents in the news and social media posts <a href="https://twitter.com/DaveMcNamee3000/status/1767636549288824990">poking fun at the company</a>, air travel is still extremely safe, and that includes Boeing.</p> <p>We can expect these issues with Boeing planes now will be corrected. The financial impact has been significant – so even a profit-driven company will demand change.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/225675/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/doug-drury-1277871">Doug Drury</a>, Professor/Head of Aviation, <a href="https://theconversation.com/institutions/cquniversity-australia-2140">CQUniversity Australia</a></em></p> <p><em>Image credits: Shutterstock</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Sunscreen: why wearing it even in winter could be a good idea

<p><em><a href="https://theconversation.com/profiles/karl-lawrence-404481">Karl Lawrence</a>, <a href="https://theconversation.com/institutions/kings-college-london-1196">King's College London</a></em></p> <p>Sunscreen has taken centre stage in many skincare routines, especially among those hoping to prevent visible signs of ageing. But while it makes sense to wear sunscreen every day in the summer when the sun’s rays are most powerful, many may wonder whether there’s any benefit of wearing sunscreen daily in the winter months.</p> <p>The sun’s radiation can reach us during all times of the year. This means that in both summer and winter, we are exposed to infrared radiation, as well as UVA and UVB rays.</p> <p>UVB is mainly responsible for sunburn and DNA damage – and can also <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3709783/">cause skin cancers</a> as a result of long-term exposure. UVA radiation does contribute to these processes somewhat, but it’s less effective at doing so. UVA can penetrate deeper into the skin, however, which can damage the collagen – a key part of the skin that keeps it firm and elastic. This can cause the <a href="https://pubmed.ncbi.nlm.nih.gov/25234829/">skin to age faster</a>, leading to wrinkles, fine lines and changes in pigmentation.</p> <p>The amount of UVA and UVB radiation that reaches the Earth’s surface changes across the seasons. This is due to the angle of the Sun in the sky, as well as other factors such as latitude and time of day.</p> <p>For example, let’s compare how <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/php.12422">UVA and UVB radiation varies</a> at solar noon in London, UK and Kuala Lampur, Malaysia (which is near the equator).</p> <p>In latitudes closer to the equator (such as in Kuala Lampur), the amount of UVA and UVB radiation throughout the year remains fairly consistent. But in higher latitudes, such as London, there’s almost no UVB radiation throughout the winter months – whereas there’s still some UVA radiation.</p> <p>Not only that, but people living further from the equator may tend to spend less time exposed to the Sun in winter due to the colder temperatures and variable weather. And when they do go outside, they may cover their skin up – usually leaving only their face exposed to the Sun for much shorter periods of time.</p> <p>But UVA radiation can still penetrate through clouds and windows. While our exposure to these rays is probably minimal, skin damage from UV exposure is <a href="https://www.sciencedirect.com/science/article/pii/S0079610706000162">accumulated over decades</a>, so anything that can be done to reduce exposure (and damage) over time may be beneficial. This is also true of UVB exposure – although it is less relevant in winter months at higher latitudes.</p> <p>This may be where daily sunscreen use during the winter is still of benefit. Sunscreens are formulated to reduce exposure to <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6978633/">both UVB and UVA rays</a> – although they are usually more effective at reducing exposure to UVB radiation. They have been designed in this way to prevent the most damaging effects of the Sun, such as sunburn and DNA damage. The impact of exposure to UVA radiation has only been considered more recently.</p> <p>Numerous studies have shown regular sunscreen use over many years is effective at <a href="https://onlinelibrary.wiley.com/doi/10.1111/phpp.12109">preventing skin damage</a>, photoaging and skin cancers. The most robust trials suggest daily sunscreen use is most effective, but this will be dependent on the factors discussed above.</p> <h2>The effects of altitude and snow</h2> <p>One place where winter sunscreen use is especially important is when skiing or snowboarding – or when you’re otherwise going to be outside for extended periods of time, at higher altitudes on snow-covered mountains.</p> <p>Both altitude and snow can increase the doses of <a href="https://www.who.int/news-room/questions-and-answers/item/radiation-ultraviolet-(uv)">UVA and UVB radiation</a> a person receives. Snow can reflect up to 80% of UV radiation emitted by the Sun – effectively almost doubling the doses received. Also, for every 1,000-foot increase in altitude, there’s a 10% increase in UV exposure. This is why it’s essential to protect the skin and eyes by wearing sunscreen, protective clothing and sunglasses that block both types of UV ray. This is also true when spending time in snowy environments, such as when hiking or skating.</p> <p>Sunscreens are generally regarded as safe and tend to have few adverse effects, so you don’t need to worry too much about wearing one throughout the year. However, there are some points to consider, especially if you have skin conditions. For example, sunscreen can <a href="https://www.byrdie.com/does-sunscreen-cause-acne-or-help-it-7546147">exacerbate acne</a> and cause <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7759112/">irritation and allergic reactions</a> – although these are rare.</p> <p>There are also emerging concerns from regulatory agencies about the <a href="https://jamanetwork.com/journals/jama/fullarticle/2759002">absorption of UV filters into the body</a>. However, the consequences of such absorption and the potential affects on health are not well defined and require more research.</p> <p>Still, the benefits of sunscreen have been widely demonstrated – as has their safety. So if you want to prevent premature signs of ageing, it’s important to use sunscreen at all times you may be exposed to the Sun – especially in the summer months. While the benefits of wearing sunscreen in winter are less well defined, there’s probably no harm in wearing one if you want to.</p> <p>If you decide to use sunscreen in winter, use ones that have broad spectrum five-star UVA protection. For day-to-day use, high SPF sunscreens are unlikely to provide a large benefit, particularly if spending only short periods outside. However, if skiing, a <a href="https://www.jaad.org/article/S0190-9622(17)31086-1/fulltext">high-SPF sunscreen</a> with five-star UVA protection would be beneficial.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/219640/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/karl-lawrence-404481"><em>Karl Lawrence</em></a><em>, Research fellow, <a href="https://theconversation.com/institutions/kings-college-london-1196">King's College London</a></em></p> <p><em>Image credits: </em><em>Getty Images </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

There may also be a level of guilt or self-indulgence associated with solo travel, feeling as if you are shirking responsibility or abandoning time with family.</p> <p>An increase in <a href="https://www.euromonitor.com/article/single-person-households-to-record-128-percent-growth-by-2030">single-person households</a>, however, means the hospitality industry is now serving solo consumers in addition to families and couples. The continuously <a href="https://www.forbes.com/sites/adigaskell/2020/05/11/is-a-blurred-work-life-balance-the-new-normal/?sh=5c9db6341813">blurred line</a> between work and play, particularly for Millennials and younger generations, makes it easier to work remotely or travel as part of our jobs. We are more transient than ever, and have more opportunities to work and travel alone without feeling completely disconnected from the rest of our lives.</p> <p>In recent years, people have been <a href="https://www.telegraph.co.uk/travel/comment/whats-behind-the-rise-in-solo-travel/">increasingly</a> travelling alone – including younger vacationers. They also share their experiences to a large audience on social media – the hashtag #SoloTravel has over 7 million posts associated with it on Instagram. Solo travellers are taking part in the growing <a href="https://www.futuresplatform.com/blog/solo-economy-new-consumption-patterns">solo economy</a> – new products and services targeting the lone consumer.</p> <p>Hotels, <a href="https://www.ncl.com/uk/en/freestyle-cruise/solo-cruising">cruises</a>, restaurants, tourism <a href="https://www.flashpack.com/">companies</a> and festivals are showing how design, staff and technology can be tailored to accommodate – and even encourage – solo consumption in travel. <a href="https://journals.sagepub.com/doi/10.1177/14705931211017184">Our research</a> into the experience of solo consumers in coffee shops offers insight into how solo consumption can be as pleasurable and fulfilling as going with a partner or friend. Through <a href="https://www.research.ucsb.edu/sites/default/files/RD/docs/FREEWRITING-by-Peter-Elbow.pdf">freewriting</a> exercises, these consumers shared their own experiences. Their words offer some reasons you should try it too.</p> <h2>Be together, alone</h2> <p>Our research participants highlighted key factors that help them enjoy their solo experience – high seats and window views allowing them to sit back and observe others’ lives without any direct interaction or connection. You don’t need to arrive with others to feel part of a social environment. Alone in a crowded square or on a busy beach, the proximity of other people and their conversations can be a source of comfort, distraction or even entertainment.</p> <blockquote> <p>The seat is important -– I like the window especially a stool and “shelf” table facing out … I see people, imagine their lives, see cars and life pass by. I watch other customers, I watch the street out the window, the cliché of “watching the world pass by”. The setting, context and environment of the café are important to that moment of pause.</p> </blockquote> <h2>Take time for yourself</h2> <p>Being alone can be a <a href="https://journals.sagepub.com/doi/pdf/10.1177/14705931211017184">therapeutic experience</a>, a time to process thoughts, feelings and emotions and leave you ready to tackle the world again. Perhaps take time to write, draw or practice another creative activity in your own time. Bask in your own thoughts without feeling pressure to please anyone else or force a conversation.</p> <blockquote> <p>Sitting alone with my thoughts can be a comforting experience; picking a seat, getting comfy…I can find silence with my thoughts and don’t feel any pressure to act for anybody or involve myself in a conversation that doesn’t interest me.</p> </blockquote> <h2>Get out of your comfort zone</h2> <p>Being able to do your own thing, without needing to consider others can be relaxing and can also give you the opportunity to do something you’ve never done before, free of judgement. You might want to go to some sort of class, shop or have a complete chill-out day.</p> <p>Findings from our research indicate that time spent doing things alone can relieve some of the pressures that companions can bring. Alone time gives you the space to experience things in your own time and take in your surroundings without distraction. In doing this, you may find yourself in new situations, away from your comfort zone – an energising and enthralling experience.</p> <h2>Embrace solo traveller culture</h2> <p>Solo travellers have their <a href="https://www.sciencedirect.com/science/article/pii/S0278431921002516">own way of doing things</a>, they have a shared behaviour and process and often become a collective in themselves. They acknowledge the process of travelling alone and respect others doing the same, and may even seek out spaces to be alone, together. Solo travellers can engage in a shared experience and dialogue while maintaining their own individualism – helping each other when needed, but also leave one another alone.</p> <blockquote> <p>We search for places where we feel we fit … We are happy to smile at one another.

Longing for the ‘golden age’ of air travel? Be careful what you wish for

<p><em><a href="https://theconversation.com/profiles/janet-bednarek-144872">Janet Bednarek</a>, <a href="https://theconversation.com/institutions/university-of-dayton-1726">University of Dayton</a></em></p> <p>Long lines at security checkpoints, tiny plastic cups of soda, small bags of pretzels, planes filled to capacity, fees attached to every amenity – all reflect the realities of 21st century commercial air travel. It’s no wonder that many travelers have become nostalgic for the so-called “golden age” of air travel in the United States.</p> <p>During the 1950s, airlines promoted commercial air travel as glamorous: stewardesses served full meals on real china, airline seats were large (and frequently empty) with ample leg-room, and passengers always dressed well.</p> <p>After jets were introduced in the late 1950s, passengers could travel to even the most distant locations at speeds unimaginable a mere decade before. An airline trip from New York to London that could take up to 15 hours in the early 1950s could be made in less than seven hours by the early 1960s.</p> <p>But airline nostalgia can be tricky, and “golden ages” are seldom as idyllic as they seem.</p> <p>Until the introduction of jets in 1958, most of the nation’s commercial planes were propeller-driven aircraft, like the DC-4. Most of these planes were unpressurized, and with a maximum cruising altitude of 10,000 to 12,000 feet, they were unable to fly over bad weather. Delays were frequent, turbulence common, and air sickness bags often needed.</p> <p>Some planes were spacious and pressurized: the <a href="http://everythingnice.org/wp-content/uploads/2009/07/PanAm-cutawayS.jpg">Boeing Stratocruiser</a>, for example, could seat 50 first class passengers or 81 coach passengers compared to the DC-3’s 21 passengers. It could cruise at 32,000 feet, which allowed Stratocruiser to fly above most bad weather it encountered. But only 56 of these planes were ever in service.</p> <p>While the later DC-6 and DC-7 were pressurized, they still flew much lower than the soon-to-appear jets – 20,000 feet compared to 30,000 feet – and often encountered turbulence. The piston engines were bulky, complex and difficult to maintain, which contributed to frequent delays.</p> <p>For much of this period, the old saying “Time to spare, go by air” still rang true.</p> <p>Through the 1930s and into the 1940s, almost everyone flew first class. Airlines did encourage more people to fly in the 1950s and 1960s by introducing coach or tourist fares, but the savings were relative: less expensive than first class, but still pricey. In 1955, for example, so-called “bargain fares” from New York to Paris were the equivalent of just over $2,600 in 2014 dollars. Although the advent of jets did result in lower fares, the cost was still out of reach of most Americans. The most likely frequent flier was a white, male businessman traveling on his company’s expense account, and in the 1960s, airlines – with young attractive stewardesses in short skirts – clearly catered to their most frequent flyers.</p> <p>The demographics of travelers did begin to shift during this period. More women, more young people, and retirees began to fly; still, airline travel remained financially out-of-reach for most.</p> <p>If it was a golden age, it only was for the very few.</p> <figure><iframe src="https://www.youtube.com/embed/bKqQgNZylLw?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption><span class="caption">Jet planes were introduced in the late 1950s, resulting in shorter flight times. But their ticket prices out of reach for the average traveler.</span></figcaption></figure> <p>People also forget that well into the 1960s, air travel was far more dangerous than it is today. In the 1950s and 1960s US airlines experienced at least a half dozen crashes per year – most leading to fatalities of all on board. People today may bemoan the crowded airplanes and lack of on-board amenities, but the number of fatalities per million miles flown has dropped dramatically since since the late 1970s, especially compared to the 1960s. Through at least the 1970s, airports even prominently featured kiosks selling flight insurance.</p> <p>And we can’t forget hijackings. By the mid-1960s so many airplanes had been hijacked that <a href="http://www.latinamericanstudies.org/hijackers/flying-high.htm">“Take me to Cuba”</a> became a punch line for stand-up comics. In 1971 <a href="http://nymag.com/news/features/39593/index2.html">D.B. Cooper</a> – a hijacker who parachuted from a Boeing 727 after extorting $200,000 – might have been able to achieve folk hero status. But one reason US airline passengers today (generally) tolerate security checkpoints is that they want some kind of assurance that their aircraft will remain safe.</p> <p>And if the previous examples don’t dull the sheen of air travel’s “golden age,” remember: in-flight smoking was both permitted and encouraged.<!-- Below is The Conversation's page counter tag.

How bad is junk food for you, really?

<p>Consuming more junk foods, such as soft drinks, packaged snacks, and sugary cereals, is associated with a higher risk of more than 30 different health problems – both physical and mental – according to researchers.</p> <p>A study, known as an umbrella review, combined the results of 45 previous meta-analyses published in the last three years, representing about 10 million participants.</p> <p>Thirty-two different poor health outcomes were found to be linked to the consumption of ultra-processed foods (UPFs), with varying levels of evidence supporting the findings.</p> <p>The researchers found the most convincing evidence around higher ultra-processed food intake, which was associated with a 50% increased risk of cardiovascular disease-related death, a 48-53% higher risk of anxiety and common mental disorders, and a 12% greater risk of type 2 diabetes.</p> <p>Evidence marked as ‘highly suggestive’ included a 21% increase in death from any cause, a 40-66% increased risk of a heart disease related death, obesity, type 2 diabetes, and sleep problems, as well as a 22% increased risk of depression.</p> <p>The review also found there may be links between ultra-processed food and asthma; gastrointestinal health; some cancers; and other risk factors such as high blood fats and low levels of ‘good’ cholesterol, but the researchers note this evidence is limited.</p> <p>Dr Daisy Coyle from the George Institute for Global Health in Sydney, who was not involved in the research, says the statistics are “staggering.”</p> <p>“Ultra-processed foods, laden with additives and sometimes lacking in essential nutrients, have become ubiquitous in the Australian diet,” she says.</p> <p>“In fact, they make up almost half of what we buy at the supermarket. While not all ultra-processed foods are linked to poor health outcomes, many are, particularly sugary drinks and processed meats.”</p> <div> </div> <p>While the findings are in line with other research that highlights the health risks associated with UPFs, some experts have pointed out that the study is observational, and therefore can’t prove the ultra-processed foods cause these health issues. It can only show an association.</p> <p>“While these associations are interesting and warrant further high-quality research, they do not and cannot provide evidence of causality,” The University of Sydney’s Dr Alan Barclay told the AusSMC.</p> <p>“By their very nature, observational studies are renowned for being confounded by numerous factors – both known and unknown.”</p> <p>Clare Collins, Laureate Professor at the University of Newcastle agreed, but added that it’s difficult to conduct dietary studies like this in a different way.</p> <p>“The studies are observational, which means cause and effect cannot be proven and that the research evidence gets downgraded, compared to intervention studies,” she says.</p> <p>“The problem is that it is not ethical to do an intervention study lasting for many years where you feed people lots of UPF every day and wait for them to get sick and die.”</p> <p>For now, researchers seem to agree that it can’t be a bad thing to minimise UPF intake.</p> <p>The review suggests a need for policies that pull consumers away from ultra-processed foods, such as advertising restrictions, warning labels, bans in schools and hospitals. It also calls for measures that make healthier foods more accessible and affordable.</p> <p>Dr Charlotte Gupta from Central Queensland University suggests that this is issue of accessibility is particularly relevant for shift workers such as doctors, nurses, firefighters, taxi drivers, miners, and hospitality workers.</p> <p>“There is a lack of availability of fresh foods or time to prepare any food, and so ultra-processed foods have to be relied on (e.g. from the vending machine in the hospital),” she said.</p> <p>“This highlights the need for not only individuals to try reducing ultra-processed foods in our diet, but also for public health actions to improve access to healthier foods.”</p> <p><em>Image credits: Shutterstock</em></p> <p><em><a href="https://cosmosmagazine.com/health/how-bad-is-junk-food-for-you-really/">This article</a> was originally published on <a href="https://cosmosmagazine.com">Cosmos Magazine</a> and was written by <a href="https://cosmosmagazine.com/contributor/olivia-henry/">Olivia Henry</a>. </em></p>

We talked to dozens of people about their experience of grief. Here’s what we learned (and how it’s different from what you might think)

<p><em><a href="https://theconversation.com/profiles/michelle-peterie-564209">Michelle Peterie</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> and <a href="https://theconversation.com/profiles/alex-broom-121063">Alex Broom</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p>Have you ever felt a sudden pang of sadness? A bird seems to stop and look you in the eye. A photo drops out of a messy drawer from long ago, in the mundanity of a weekend spring clean.</p> <p>Your day is immediately derailed, unsettled. You are pulled into something you thought was past. And yet, in being pulled back, you are grateful, reconnected, and grief-stricken all over again.</p> <p>“You’ll get over it”. “Give it time”. “You need time to move on”. These are common cultural refrains in the face of loss. But what if grief doesn’t play by the rules? What if grief is a different thing altogether?</p> <p>We talked to 95 people about their experiences of grief surrounding the loss of a loved one, and <a href="https://journals.sagepub.com/doi/10.1177/00380261241228412">their stories</a> provided a fundamentally different account of grief to the one often presented to us culturally.</p> <h2>Disordered grief?</h2> <p>Grief is often imagined as a time-bound period in which one processes the pain of loss – that is, adjusts to absence and works toward “moving on”. The bereaved are expected to process their pain within the confines of what society deems “normal”.</p> <p>The <a href="https://theconversation.com/explainer-what-is-the-dsm-and-how-are-mental-disorders-diagnosed-9568">DSM-5 psychiatric manual</a> says if grief drags on too long, in fact, it becomes a pathology (a condition with a medical diagnosis). “Prolonged grief disorder” is the name given to “persistent difficulties associated with bereavement that exceeded expected social, cultural, or religious expectations”.</p> <p>While there can be <a href="https://theconversation.com/why-prolonged-grief-should-be-listed-as-a-mental-disorder-4262">value</a> in clinical diagnostic categories such as this, the danger is they put artificial boundaries around emotions. The pathologisation of grief can be deeply alienating to those experiencing it, for whom the pressure to “move on” can be hurtful and counterproductive.</p> <p>The stories we gathered in our research were raw, complex and often fraught. They did not sit comfortably with commonsense understandings of how grief “should” progress. As bereaved daughter Barbara told us: "Grief is not in the little box, it doesn’t even come close to a little box."</p> <h2>Grief starts early</h2> <p>The tendency is to think of grief as something that happens post death. The person we love dies, we have a funeral, and the grief sets in. Then it slowly subsides with the steady march of time.</p> <p>In fact, grief often begins earlier, often in a clinical consultation where the words “terminal” or “nothing more we can do” are used. Or when a loved one is told “go home and get your life in order”. Grief can begin months or even years before bereavement.</p> <p>As the people we interviewed experienced it, loss was also cumulative. The gradual deterioration of a loved one’s health in the years or months before their death imposed other painful losses: the loss of chosen lifestyles, the loss of longstanding relational rhythms, the loss of shared hopes and anticipated futures.</p> <p>Many participants felt their loved ones – and, indeed, the lives they shared with them – slipping away long before their physical deaths.</p> <h2>Living with the dead</h2> <p>Yet the dead do not simply leave us. They remain with us, in memories, rituals and cultural events. From <a href="https://theconversation.com/what-ancient-cultures-teach-us-about-grief-mourning-and-continuity-of-life-86199">Mexico’s Dia de los Muertos</a> to <a href="https://theconversation.com/japans-obon-festival-how-family-commemoration-and-ancestral-worship-shapes-daily-life-179890">Japan’s Opon</a>, festivals of the dead play a key role in cultures around the world. In that way, remembering the dead remains a critical aspect of living. So too does <a href="https://theconversation.com/theres-not-always-closure-in-the-never-ending-story-of-grief-3096">the ongoing experience of grief</a>.</p> <p>Events of this kind are not merely celebratory. They are critical forms through which life and death, joy and grief, are brought together and integrated. The absence of remembering can hold its own trouble, as our participants’ accounts revealed. </p> <p>As bereaved wife Anna explained: "I just find it really frustrating and I do get quite angry and upset sometimes. I know that life goes on. I’d be talking to girlfriends and stuff like that and it’s like they’ve forgotten that I’ve lost my husband. They haven’t, but nothing really changed in their life. But for me, and my family, it has."</p> <p>Part of the problem, here, is the ambivalent role grief plays in advanced industrialised societies like ours. Many of our participants felt pressure to perform resilience or (in clinical terms) to <a href="https://journals.sagepub.com/doi/full/10.1177/1363459317724854">“recover” quickly after loss</a>.</p> <p>But whose interests does a swift recovery serve? An employer’s? Friends who just want to get on with a death-free life? And, even more importantly, mightn’t ongoing connections with the dead enable better living? Might bringing the dead along with us actually make for better deaths and better lives?</p> <p>Many of our participants felt their loved ones remained with them, and experienced their “absent presence” as a source of comfort. Grieving, in this context, involved spending time “with” the dead. </p> <p>Anna described her practice as follows: "I had a diary, so I just write stuff in it about how I’m feeling or something happened and I’ll say to [my deceased husband], it’s all to [my deceased husband], “Do you remember, blah, blah, blah.” I’ll just talk about that memory that I have of that particular time and I find that that helps."</p> <h2>Caring for those who grieve</h2> <p>Grief does not begin at death, but neither do relationships end there.</p> <p>To rush the bereaved through grief – to usher them towards “recovery” and the more comfortable territories of happiness and productivity – is to do them a disservice.</p> <p>And, perhaps more critically, ridding our lives of the dead and grief may, in the end, make for more limited and muted emotional lives.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/223848/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/michelle-peterie-564209"><em>Michelle Peterie</em></a><em>, Research Fellow, Sydney Centre for Healthy Societies, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> and <a href="https://theconversation.com/profiles/alex-broom-121063">Alex Broom</a>, Professor of Sociology &amp; Director, Sydney Centre for Healthy Societies, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p><em>Image credits: Getty Images </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Foods to avoid if you have acid reflux or digestion issues

<p><strong>What common foods are good and bad for your belly?</strong></p> <p>Foods containing rapidly fermentable carbohydrates called FODMAPs can feed bacteria in the gut and may be responsible for gut inflammation, gas, bloating and other uncomfortable tummy troubles in some people. Cutting back on foods that contain FODMAPs may help improve your digestion and eliminate GI problems. </p> <p>“An anti-inflammatory diet is high in fibre-rich foods, which promote the growth of healthy bacteria in the gut (one way the diet assists to control inflammation),” says registered dietitian Maxine Smith. A FODMAP diet, which is low in fermentable carbohydrates, is low in fibre and may be beneficial for some people with gastrointestinal problems. </p> <p>In general, a low FODMAPs diet isn’t recommended for people unless they have a condition like irritable bowel syndrome that hasn’t responded to other treatments or dietary changes.</p> <p><strong>Watermelon: Avoid</strong></p> <p>This lovely summer treat isn’t as harmless as all the water it contains. Watermelon is high in fructose, fructans and polyols, which are FODMAPs. Remember, the more the FODMAPs, the more potential for tummy trouble in people who are sensitive to them.</p> <p><strong>Fermented foods: Enjoy some, avoid some</strong></p> <p>Some fermented foods are good for your tummy; others can create problems for certain people, according to an article published by Harvard Medical School. Fermented foods include wine, cheese, vinegar, miso, yoghurt, sauerkraut and pickles. </p> <p>In yoghurt, milk is combined with bacteria that break down some of the lactose, so what remains may be easier for your stomach to process. So fermented foods such as yoghurt are often considered “probiotic foods” that are good for your gut. Look for dairy products that are low in lactose and your digestion should be A-OK.</p> <p><strong>Pistachios, cashews, hazelnuts and almonds: Avoid</strong></p> <p>Most nuts are good for your tummy, but pistachios and cashews are high in fructans and GOS (galacto-oligosaccharides), both FODMAPs. Hazelnuts and almonds are a little higher in FODMAPs than some other nuts so eat them in limited quantities (10 nuts or 1 tablespoon of nut butter per serving). Steer clear of almond milk, which is made with large amounts of almonds.</p> <p><strong>Acidic foods: Enjoy with caution</strong></p> <p>In almost every list of “the worst foods for digestion,” you’ll find acidic foods like oranges and tomatoes. These are commonly thought to cause heartburn, but studies have shown that acidic foods don’t have any effect on LES pressure (or pressure on the lower oesophageal sphincter, a valve that acts as the doorway between the oesophagus and the stomach) and don’t cause heartburn symptoms. </p> <p>However, if you have severe acid reflux that hasn’t been treated and has irritated the oesophagus, acidic foods can be like “salt in the wound.” So if you find that oranges or tomatoes do make your heartburn feel worse, replace them with other fruits.</p> <p><strong>Dairy foods: Enjoy some, avoid some</strong></p> <p>Not all dairy foods have equal amounts of lactose, which can cause digestion issues, and even those with lactose intolerance are usually okay with small amounts of lactose. That means that not all milk, cheeses and dairy products are tummy twisters. </p> <p>Hard cheeses, like cheddar, Swiss or Parmesan, generally have less than a gram of lactose per serving. According to the Cleveland Clinic, you may want to avoid dairy such as “chocolate shakes or drinks, milkshakes, whole milk fat yoghurt, whole milk fat (4%) cottage cheese, and full-fat cheese.”</p> <p><strong>Soy foods: Enjoy some, avoid some</strong></p> <p>Whole soybeans (often sold as edamame), like other beans, are a source of GOS, which are hard-to-digest chains of sugars. Tofu and tempeh are made using processes that eliminate some of the GOS, making them easier on your digestion. What about soy milk? It depends. </p> <p>If soy milk is made with only soybean isolates or soy protein, then it should be low in FODMAPs. Soy milk made with whole soybeans is likely a source of GOS, making it a gassy beverage for some, so read the ingredients.</p> <p><strong>Blackberries: Avoid</strong></p> <p>Strawberries, blueberries, blackberries – which is the odd one out here? Blackberries are also rich in antioxidants, but they have sugar alcohols called polyols, which are difficult to digest and can cause some real problems if your stomach is sensitive. (Check out these foods that GI doctors always avoid.)</p> <p><strong>Tomato and tomato products: Enjoy some, avoid some</strong></p> <p>Fresh and canned tomatoes are fine for your tummy. But tomato paste is a concentrated form of tomato that has excess fructose, a FODMAP that makes it a no-no except in small quantities. And tomato sauces? If they’re homemade, they’re fine to eat (just don’t cook it to the point where all the juices are lost). </p> <p>Most commercial sauces have onions and garlic (FODMAPs), added sugar (which may make it carb-dense), and salt (which bloats you), so steer clear of the store-bought variety.</p> <p><strong>Grapefruit: Enjoy with caution</strong></p> <p>Grapefruit does have hard-to-digest fructans, so you should try to limit how much you eat. A few sections should be okay, but don’t eat a half a grapefruit. If you’re looking for citrus, lemon, lime and oranges are your best bets.</p> <p><strong>Milk: Enjoy some, avoid some</strong></p> <p>Most types of animal milk are high in tummy twisting lactose – that means goat’s or sheep’s milk can be just as problematic as cow’s milk. Plant-based milks, such as coconut milk, soy milk or almond milk, are technically not milk at all and generally do not have any lactose. </p> <p>Some, however, including almond milk and soy milk, may contain other FODMAPs that harm your digestion.</p> <p><strong>Corn: Avoid</strong></p> <p>Corn comes in many varieties, such as popcorn, on the cob and in polenta. Fresh sweet corn contains two types of FODMAPs, making corn challenging for some people to digest. Popcorn feels like a light and healthy snack, but it’s actually carb-dense (it has about 64 grams of carbs per 100 grams), which can upset digestion. </p> <p>Whole cornmeal and corn tortillas seem to be better tolerated by most people. Whole grain polenta is also low in FODMAPs. You may need to experiment a little to figure out which corn products work for you. And stick with only limited quantities (up to 1 cup cooked per serving).</p> <p><strong>Common cabbage: Enjoy</strong></p> <p>Cabbage usually makes it on all the lists of foods that make you gassy, but common green cabbage doesn’t deserve that reputation. It’s actually low in FODMAPs and most of us break it down very well. </p> <p>Red cabbage also seems to be well-tolerated, but savoy and napa cabbage is much higher in FODMAPs and should be limited if you tend to suffer from gas and bloating.</p> <p><strong>Hot sauce: Enjoy with caution</strong></p> <p>Tolerance to hot sauce is very individual. It’s more problematic for those with heartburn. If you would like to try some, pick a brand without onion and garlic.</p> <p><em>Image credits: Getty Images </em></p> <p><em>This article originally appeared on <a href="https://www.readersdigest.co.nz/healthsmart/conditions/foods-to-avoid-if-you-have-acid-reflux-or-digestion-issues?pages=1" target="_blank" rel="noopener">Reader's Digest</a>.</em></p>

The one thing you must do before retirement

<p>When you think about planning for retirement, the standard advice is to take a thorough look at your superannuation and finances. Although money is undoubtedly an important aspect of retirement planning, making a plan for your emotion and physical wellbeing is just as crucial.</p> <p>New research from the UK has found that retirement can have a negative impact on your mental and physical health. The study, published by the Institute of Economic Affairs, looked at the impact of retirement on 7,000 people aged 50 to 70, and found that while retirement gives most people a small health booth, over the medium to long-term it causes a “drastic decline in health”. </p> <p>For both men and women, retirement decreases the likelihood of "very good” or "excellent" self-reported health by 40 per cent, increases risk for depression by 40 per cent, and diagnosis of a physical illness by 60 per cent. The study’s lead author, Gabriel Sahlgren, noted: "Work, especially paid work, gives many people a sense of purpose. Losing that may lead to declines in health."</p> <p>The lesson: Make a plan for your emotional and physical health.</p> <p>“Don't wait until you retire to decide how you're going to keep busy,” Dave Bernard, retirement blogger and author of Are You Just Existing and Calling it a Life?, told Prevention, adding, “And you need to look well beyond the first six months.”</p> <p>Just as it’s necessary to make sure your finances are in order before retirement, it’s crucial to ask yourself: What will my new sense of purpose in retirement be?</p> <p>“Many times, adults might not think about what it actually means to be retired, or they think about retirement in abstract terms,” says Angela Curl, an assistant professor in the University of Missouri School of Social Work.</p> <p>She says you need to make concrete plans for retirement. “If you want to volunteer when you are retired, ask yourself where and how often. Having specific plans and steps to follow will help you enter retirement more easily,” says Curl.</p> <p>Creating a plan of how you’ll spend your time when you retire will keep you mentally and physically strong, ensuring that you’ll be healthy enough to enjoy your well-deserved retirement.</p> <p><em>Image credits: Getty Images </em></p>

Running or yoga can help beat depression, research shows – even if exercise is the last thing you feel like

<p><em><a href="https://theconversation.com/profiles/michael-noetel-147460">Michael Noetel</a>, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a></em></p> <p>At least <a href="https://www.frontiersin.org/journals/psychiatry/articles/10.3389/fpsyt.2021.665019/full">one in ten people</a> have depression at some point in their lives, with some estimates <a href="https://www.sciencedirect.com/science/article/pii/S0749379720301793">closer to one in four</a>. It’s one of the worst things for someone’s wellbeing – worse than <a href="https://www.happinessresearchinstitute.com/_files/ugd/928487_4a99b6e23f014f85b38495b7ab1ac24b.pdf">debt, divorce or diabetes</a>.</p> <p><a href="https://theconversation.com/why-are-so-many-australians-taking-antidepressants-221857">One in seven</a> Australians take antidepressants. Psychologists are in <a href="https://theconversation.com/we-cant-solve-australias-mental-health-emergency-if-we-dont-train-enough-psychologists-here-are-5-fixes-190135">high demand</a>. Still, only <a href="http://dx.doi.org/10.1371/journal.pmed.1003901">half</a> of people with depression in high-income countries get treatment.</p> <p>Our <a href="https://www.bmj.com/content/384/bmj-2023-075847">new research</a> shows that exercise should be considered alongside therapy and antidepressants. It can be just as impactful in treating depression as therapy, but it matters what type of exercise you do and how you do it.</p> <h2>Walk, run, lift, or dance away depression</h2> <p>We found 218 randomised trials on exercise for depression, with 14,170 participants. We analysed them using a method called a network meta-analysis. This allowed us to see how different types of exercise compared, instead of lumping all types together.</p> <p>We found walking, running, strength training, yoga and mixed aerobic exercise were about as effective as <a href="https://theconversation.com/explainer-what-is-cognitive-behaviour-therapy-37351">cognitive behaviour therapy</a> – one of the <a href="https://www.frontiersin.org/journals/psychiatry/articles/10.3389/fpsyt.2018.00004/full">gold-standard treatments</a> for depression. The effects of dancing were also powerful. However, this came from analysing just five studies, mostly involving young women. Other exercise types had more evidence to back them.</p> <p>Walking, running, strength training, yoga and mixed aerobic exercise seemed more effective than antidepressant medication alone, and were about as effective as exercise alongside antidepressants.</p> <p>But of these exercises, people were most likely to stick with strength training and yoga.</p> <p><iframe id="cZaWb" class="tc-infographic-datawrapper" style="border: none;" src="https://datawrapper.dwcdn.net/cZaWb/2/" width="100%" height="400px" frameborder="0"></iframe></p> <p>Antidepressants certainly help <a href="https://www.thelancet.com/article/S0140-6736(17)32802-7/fulltext">some people</a>. And of course, anyone getting treatment for depression should talk to their doctor <a href="https://australia.cochrane.org/news/new-cochrane-review-explores-latest-evidence-approaches-stopping-long-term-antidepressants">before changing</a> what they are doing.</p> <p>Still, our evidence shows that if you have depression, you should get a psychologist <em>and</em> an exercise plan, whether or not you’re taking antidepressants.</p> <h2>Join a program and go hard (with support)</h2> <p>Before we analysed the data, we thought people with depression might need to “ease into it” with generic advice, <a href="https://www.who.int/initiatives/behealthy/physical-activity">such as</a> “some physical activity is better than doing none.”</p> <p>But we found it was far better to have a clear program that aimed to push you, at least a little. Programs with clear structure worked better, compared with those that gave people lots of freedom. Exercising by yourself might also make it hard to set the bar at the right level, given low self-esteem is a symptom of depression.</p> <p>We also found it didn’t matter how much people exercised, in terms of sessions or minutes a week. It also didn’t really matter how long the exercise program lasted. What mattered was the intensity of the exercise: the higher the intensity, the better the results.</p> <h2>Yes, it’s hard to keep motivated</h2> <p>We should exercise caution in interpreting the findings. Unlike drug trials, participants in exercise trials know which “treatment” they’ve been randomised to receive, so this may skew the results.</p> <p>Many people with depression have physical, psychological or social barriers to participating in formal exercise programs. And getting support to exercise isn’t free.</p> <p>We also still don’t know the best way to stay motivated to exercise, which can be even harder if you have depression.</p> <p>Our study tried to find out whether things like setting exercise goals helped, but we couldn’t get a clear result.</p> <p>Other reviews found it’s important to have a <a href="https://pubmed.ncbi.nlm.nih.gov/31923898/">clear action plan</a> (for example, putting exercise in your calendar) and to <a href="https://pubmed.ncbi.nlm.nih.gov/19916637/">track your progress</a> (for example, using an app or smartwatch). But predicting which of these interventions work is notoriously difficult.</p> <p>A <a href="https://www.nature.com/articles/s41586-021-04128-4">2021 mega-study</a> of more than 60,000 gym-goers <a href="https://www.nature.com/articles/s41586-021-04128-4/figures/1">found</a> experts struggled to predict which strategies might get people into the gym more often. Even making workouts fun didn’t seem to motivate people. However, listening to audiobooks while exercising helped a lot, which no experts predicted.</p> <p>Still, we can be confident that people benefit from personalised support and accountability. The support helps overcome the hurdles they’re sure to hit. The accountability keeps people going even when their brains are telling them to avoid it.</p> <p>So, when starting out, it seems wise to avoid going it alone. Instead:</p> <ul> <li> <p>join a fitness group or yoga studio</p> </li> <li> <p>get a trainer or an exercise physiologist</p> </li> <li> <p>ask a friend or family member to go for a walk with you.</p> </li> </ul> <p>Taking a few steps towards getting that support makes it more likely you’ll keep exercising.</p> <h2>Let’s make this official</h2> <p>Some countries see exercise as a backup plan for treating depression. For example, the American Psychological Association only <a href="https://www.apa.org/depression-guideline/">conditionally recommends</a> exercise as a “complementary and alternative treatment” when “psychotherapy or pharmacotherapy is either ineffective or unacceptable”.</p> <p>Based on our research, this recommendation is withholding a potent treatment from many people who need it.</p> <p>In contrast, The Royal Australian and New Zealand College of Psychiatrists <a href="https://www.ranzcp.org/getmedia/a4678cf4-91f5-4746-99d4-03dc7379ae51/mood-disorders-clinical-practice-guideline-2020.pdf">recommends</a> vigorous aerobic activity at least two to three times a week for all people with depression.</p> <p>Given how common depression is, and the number failing to receive care, other countries should follow suit and recommend exercise alongside front-line treatments for depression.</p> <p><em>I would like to acknowledge my colleagues Taren Sanders, Chris Lonsdale and the rest of the coauthors of the paper on which this article is based.</em></p> <p><em>If this article has raised issues for you, or if you’re concerned about someone you know, call Lifeline on 13 11 14.</em><!-- Below is The Conversation's page counter tag.

What ‘psychological warfare’ tactics do scammers use, and how can you protect yourself?

<p><em><a href="https://theconversation.com/profiles/mike-johnstone-106590">Mike Johnstone</a>, <a href="https://theconversation.com/institutions/edith-cowan-university-720">Edith Cowan University</a> and <a href="https://theconversation.com/profiles/georgia-psaroulis-1513050">Georgia Psaroulis</a>, <a href="https://theconversation.com/institutions/edith-cowan-university-720">Edith Cowan University</a></em></p> <p>Not a day goes by without a headline <a href="https://www.vice.com/en/article/qjvaym/people-share-worst-scam-stories">about a victim being scammed</a> and losing money. We are constantly warned about new scams and staying safe from cybercriminals. Scamwatch has <a href="https://www.scamwatch.gov.au/research-and-resources/tools-resources/online-resources/spot-the-scam-signs">no shortage of resources</a>, too.</p> <p>So why are people still getting scammed, and sometimes spectacularly so?</p> <p>Scammers use sophisticated psychological techniques. They exploit our deepest human vulnerabilities and bypass rational thought to tap into our emotional responses.</p> <p>This “<a href="https://www.thecut.com/article/amazon-scam-call-ftc-arrest-warrants.html">psychological warfare</a>” coerces victims into making impulsive decisions. Sometimes scammers spread their methods around many potential victims to see who is vulnerable. Other times, criminals focus on a specific person.</p> <p>Let’s unpack some of these psychological techniques, and how you can defend against them.</p> <h2>1. Random phone calls</h2> <p>Scammers start with small requests to establish a sense of commitment. After agreeing to these minor requests, we are more likely to comply with larger demands, driven by a desire to act consistently.</p> <p>The call won’t come from a number in your contacts or one you recognise, but the scammer may pretend to be someone you’ve engaged to work on your house, or perhaps one of your children using a friend’s phone to call you.</p> <p>If it is a scammer, maybe keeping you on the phone for a long time gives them an opportunity to find out things about you or people you know. They can use this info either immediately or at a later date.</p> <h2>2. Creating a sense of urgency</h2> <p>Scammers fabricate scenarios that require immediate action, like claiming a bank account is at risk of closure or an offer is about to expire. This tactic aims to prevent victims from assessing the situation logically or seeking advice, pressuring them into rushed decisions.</p> <p>The scammer creates an artificial situation in which you are frightened into doing something you wouldn’t ordinarily do. Scam calls <a href="https://theconversation.com/we-have-filed-a-case-under-your-name-beware-of-tax-scams-theyll-be-everywhere-this-eofy-162171">alleging to be from the Australian Tax Office</a> (ATO) are a great example. You have a debt to pay (apparently) and things will go badly if you don’t pay <em>right now</em>.</p> <p>Scammers play on your emotions to provoke reactions that cloud judgement. They may threaten legal trouble to instil fear, promise high investment returns to exploit greed, or share fabricated distressing stories to elicit sympathy and financial assistance.</p> <h2>3. Building rapport with casual talk</h2> <p>Through extended conversation, scammers build a psychological commitment to their scheme. No one gets very far by just demanding your password, but it’s natural to be friendly with people who are friendly towards us.</p> <p>After staying on the line for long periods of time, the victim also becomes cognitively fatigued. This not only makes the victim more open to suggestions, but also isolates them from friends or family who might recognise and counteract the scam.</p> <h2>4. Help me to help you</h2> <p>In this case, the scammer creates a situation where they help you to solve a real or imaginary problem (that they actually created). They work their “IT magic” and the problem goes away.</p> <p>Later, they ask you for something you wouldn’t normally do, and you do it because of the “social debt”: they helped you first.</p> <p>For example, a hacker might attack a corporate network, causing it to slow down. Then they call you, pretending to be from your organisation, perhaps as a recent hire not yet on the company’s contact list. They “help” you by turning off the attack, leaving you suitably grateful.</p> <p>Perhaps a week later, they call again and ask for sensitive information, such as the CEO’s password. You <em>know</em> company policy is to not divulge it, but the scammer will ask if you remember them (of course you do) and come up with an excuse for why they really need this password.</p> <p>The balance of the social debt says you will help them.</p> <h2>5. Appealing to authority</h2> <p>By posing as line managers, officials from government agencies, banks, or other authoritative bodies, scammers exploit our natural tendency to obey authority.</p> <p>Such scams operate at varying levels of sophistication. The simple version: your manager messages you with an <em>urgent</em> request to purchase some gift cards and send through their numbers.</p> <p>The complex version: your manager calls and asks to urgently transfer a large sum of money to an account you don’t recognise. You do this because <a href="https://www.wsj.com/articles/fraudsters-use-ai-to-mimic-ceos-voice-in-unusual-cybercrime-case-11567157402">it sounds exactly</a> like your manager on the phone – but the scammer <a href="https://www.forbes.com/sites/thomasbrewster/2021/10/14/huge-bank-fraud-uses-deep-fake-voice-tech-to-steal-millions/?sh=1329b80e7559">is using a voice deepfake</a>. In a recent major case in Hong Kong, such a scam even involved a <a href="https://edition.cnn.com/2024/02/04/asia/deepfake-cfo-scam-hong-kong-intl-hnk/index.html">deepfake video call</a>.</p> <p>This is deeply challenging because artificial intelligence tools, such as Microsoft’s VALL-E, can create <a href="https://arstechnica.com/information-technology/2023/01/microsofts-new-ai-can-simulate-anyones-voice-with-3-seconds-of-audio/">a voice deepfake</a> using just three seconds of sampled audio from a real person.</p> <h2>How can you defend against a scam?</h2> <p>First and foremost, <strong>verify identity</strong>. Find another way to contact the person to verify who they are. For example, you can call a generic number for the business and ask to be connected.</p> <p>In the face of rampant voice deepfakes, it can be helpful to <strong>agree on a “safe word” with your family members</strong>. If they call from an unrecognised number and you don’t hear the safe word just hang up.</p> <p>Watch out for <strong>pressure tactics</strong>. If the conversation is moving too fast, remember that someone else’s problem is not yours to solve. Stop and run the problem past a colleague or family member for a sanity check. A legitimate business will have no problem with you doing this.</p> <p>Lastly, if you are not sure about even the slightest detail, the simplest thing is to hang up or not respond. If you really owe a tax debt, the ATO will write to you.<!-- Below is The Conversation's page counter tag.

Your unique smell can provide clues about how healthy you are

<p><em><a href="https://theconversation.com/profiles/aoife-morrin-1478132">Aoife Morrin</a>, <a href="https://theconversation.com/institutions/dublin-city-university-1528">Dublin City University</a></em></p> <p>Hundreds of chemicals stream from our bodies into the air every second. These chemicals release into the air easily as they have high vapour pressures, meaning they boil and turn into gases at room temperature. They give clues about who we are, and how healthy we are.</p> <p>Since ancient Greek times, we’ve known that we smell differently when we are unwell. While we rely on blood analysis today, ancient Greek physicians used smell to diagnose maladies. If they took a whiff of your breath and described it as <em>fetor hepaticus</em> (meaning bad liver), it meant you could be headed for liver failure.</p> <p>If a person’s whiff was sweet or fruity, physicians thought this meant that sugars in the digestive system were not being broken down, and that person had probably diabetes.

They are also emitted from skin, urine and faeces.</p> <p>VOCs from skin are the result of millions of skin glands removing metabolic waste from the body, as well as waste generated by bacteria and other microbes that live on our skin. Sweating produces extra nutrients for these bacteria to metabolise which can result in particularly odorous VOCs. Odour from sweat only makes up a fraction of the scents from VOCs though.</p> <p><a href="https://www.nature.com/articles/nrmicro.2017.157">Our skin</a> and also our gut microbiomes are made up from a delicate balance of these microbes.

We use mass spectrometry to see this as the average human nose is not sophisticated enough to detect these VOCs.</p> <p>We can also predict a person’s age with reasonable accuracy to within a few years from their skin VOC profile. This is not surprising considering that oxidative stress in our bodies increases as we age.</p> <p><a href="https://www.metabolismjournal.com/article/S0026-0495(00)80077-3/pdf">Oxidative stress</a> happens when your antioxidant levels are low and causes irreversible damage to our cells and organs. <a href="https://pubs.acs.org/doi/10.1021/jasms.3c00315">Our recent research</a> found by-products of this oxidative damage in skin VOC profiles.</p> <p>Not only are these VOCs responsible for personal scent – they are used by plants, insects and animals as a communication channel. Plants are in a <a href="https://www.nature.com/articles/s41598-017-10975-x">constant VOC dialogue</a> with other organisms including pollinators, herbivores, other plants and their natural enemies such as harmful bacteria and insects. VOCs used for this back and forth dialogue are known as pheromones.</p> <h2>What has science shown about love pheromones?</h2> <p>In the animal kingdom, there is good evidence VOCs can act as aphrodisiacs. Mice for example have microbes which contribute to a particularly <a href="https://www.sciencedirect.com/science/article/pii/S0960982212012687">smelly compound called trimethylamine</a>, which allows mice to verify the species of a potential mate. <a href="https://www.sciencedirect.com/science/article/abs/pii/S0093691X21003083">Pigs</a> and <a href="https://www.nature.com/articles/4381097a">elephants</a> have sex pheromones too.</p> <p>It is possible that humans also produce VOCs for attracting the perfect mate. Scientists have yet to fully decode skin – or other VOCs that are released from our bodies. But evidence for human love pheromones so far is <a href="https://www.science.org/content/article/do-human-pheromones-actually-exist">controversial at best</a>. <a href="https://www.newscientist.com/article/dn3835-colour-vision-ended-human-pheromone-use/">One theory suggests</a> that they were lost about 23 million years ago when primates developed full colour vision and started relying on their enhanced vision to choose a mate.</p> <p>However, we believe that whether human pheromones exist or not, skin VOCs can reveal who and how we are, in terms of things like ageing, nutrition and fitness, fertility and even stress levels. This signature probably contains markers we can use to monitor our health and diagnose disease.<!-- Below is The Conversation's page counter tag.

What is doxing, and how can you protect yourself?

<p><em><a href="https://theconversation.com/profiles/rob-cover-13135">Rob Cover</a>, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a></em></p> <p>The Australian government has brought forward <a href="https://www.theguardian.com/australia-news/2024/feb/12/albanese-government-to-propose-legislation-to-crack-down-on-doxing">plans to criminalise doxing</a>, bringing nationwide attention to the harms of releasing people’s private information to the wider public.</p> <p>The government response comes after the <a href="https://www.smh.com.au/national/hundreds-of-jewish-creatives-have-names-details-taken-in-leak-published-online-20240208-p5f3if.html">public release of almost 600 names</a> and private chat logs of a WhatsApp group of Australian Jewish creative artists discussing the Israel-Hamas war.</p> <p>As a result, some of the people whose details were leaked claim they were harassed, <a href="https://www.theguardian.com/australia-news/2024/feb/09/josh-burns-jewish-whatsapp-group-channel-publication-israel-palestine-clementine-ford">received death threats</a> and even had to go into hiding.</p> <p>While we wait for <a href="https://www.smh.com.au/national/australia-news-live-federal-laws-on-doxxing-to-be-brought-forward-anniversary-of-stolen-generations-apology-20240213-p5f4eh.html?post=p55nen#p55nen">new penalties</a> for doxers under the federal Privacy Act review, understanding doxing and its harms can help. And there are also steps we can all take to minimise the risk.</p> <h2>What is doxing?</h2> <p><a href="https://www.kaspersky.com/resource-center/definitions/what-is-doxing">Doxing</a> (or doxxing) is releasing private information — or “docs”, short for documents — online to the wider public without the user’s consent. This includes information that may put users at risk of harm, especially names, addresses, employment details, medical or financial records, and names of family members.</p> <p>The Australian government <a href="https://ministers.ag.gov.au/media-centre/transcripts/media-conference-parliament-house-13-02-2024">currently defines doxing</a> as the “malicious release” of people’s private information without their consent.</p> <p>Doxing began as a form of unmasking anonymous users, trolls and those using hate speech while <a href="https://www.theatlantic.com/technology/archive/2022/04/doxxing-meaning-libs-of-tiktok/629643/">hiding behind a pseudonym</a>. Recently, it has become a weapon for online abuse, harassment, hate speech and adversarial politics. It is often the outcome of online arguments or polarised public views.</p> <p>It is also becoming more common. Although there is no data for Australia yet, according to media company <a href="https://www.safehome.org/family-safety/doxxing-online-harassment-research/">SafeHome.org</a>, about 4% of Americans report having been doxed, with about half saying their private emails or home addresses have been made public.</p> <p>Doxing is a crime in some countries such as the Netherlands and South Korea. In other places, including Australia, privacy laws haven’t yet caught up.</p> <h2>Why is doxing harmful?</h2> <p>In the context of the <a href="https://theconversation.com/au/topics/israel-hamas-war-146714">Israel-Hamas war</a>, doxing has affected <a href="https://www.haaretz.com/world-news/asia-and-australia/2024-02-06/ty-article/death-threats-boycotts-target-jewish-creatives-in-australia/0000018d-7e43-d636-adef-7eefae580000">both Jewish</a> and <a href="https://edition.cnn.com/2023/10/15/business/palestinian-americans-activists-doxxing/index.html">pro-Palestinian communities and activists</a> in Australia and abroad.</p> <p>Doxing is harmful because it treats a user as an object and takes away their agency to decide what, and how much, personal information they want shared with the wider public.</p> <p>This puts people at very real risk of physical threats and violence, particularly when public disagreement becomes heated. From a broader perspective, doxing also damages the digital ecology, reducing people’s ability to freely participate in public or even private debate through social media.</p> <p>Although doxing is sometimes just inconvenient, it is often used to publicly shame or humiliate someone for their private views. This can take a toll on a person’s mental health and wellbeing.</p> <p>It can also affect a person’s employment, especially for people whose employers require them to keep their attitudes, politics, affiliations and views to themselves.</p> <p>Studies have shown doxing particularly impacts <a href="https://journals.sagepub.com/doi/full/10.1177/0306422015605714">women</a>, including those using dating apps or experiencing family violence. In some cases, children and family members have been threatened because a high-profile relative has been doxed.</p> <p>Doxing is also harmful because it oversimplifies a person’s affiliations or attitudes. For example, releasing the names of people who have joined a private online community to navigate complex views can represent them as only like-minded stereotypes or as participants in a group conspiracy.</p> <h2>What can you do to protect yourself from doxing?</h2> <p>Stronger laws and better platform intervention are necessary to reduce doxing. Some experts believe that the fear of <a href="https://dl.acm.org/doi/abs/10.1145/3476075">punishment</a> can help shape better online behaviours.</p> <p>These punishments may include criminal <a href="https://www.esafety.gov.au/report/what-you-can-report-to-esafety">penalties</a> for perpetrators and <a href="https://www.theaustralian.com.au/breaking-news/doxxing-attack-on-jewish-australians-prompts-call-for-legislative-change/news-story/9a2f3615dbf5594fb521a8959739e1f8#:%7E:text=Alongside%20legislative%20reform%2C%20the%20ECAJ,information%2C%E2%80%9D%20Mr%20Aghion%20said.">deactivating social media accounts</a> for repeat offenders. But better education about the risks and harms is often the best treatment.</p> <p>And you can also protect yourself without needing to entirely withdraw from social media:</p> <ol> <li> <p>never share a home or workplace address, phone number or location, including among a private online group or forum with trusted people</p> </li> <li> <p>restrict your geo-location settings</p> </li> <li> <p>avoid giving details of workplaces, roles or employment on public sites not related to your work</p> </li> <li> <p>avoid adding friends or connections on social media services of people you do not know</p> </li> <li> <p>if you suspect you risk being doxed due to a heated online argument, temporarily shut down or lock any public profiles</p> </li> <li> <p>avoid becoming a target by pursuing haters when it reaches a certain point. Professional and courteous engagement can help avoid the anger of those who might disagree and try to harm you.</p> </li> </ol> <p>Additionally, hosts of private online groups must be very vigilant about who joins a group. They should avoid the trap of accepting members just to increase the group’s size, and appropriately check new members (for example, with a short survey or key questions that keep out people who may be there to gather information for malicious purposes).</p> <p>Employers who require their staff to have online profiles or engage with the public should provide information and strategies for doing so safely. They should also provide immediate support for staff who have been doxed.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/223428/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/rob-cover-13135"><em>Rob Cover</em></a><em>, Professor of Digital Communication and Co-Director of the RMIT Digital Ethnography Research Centre, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a></em></p> <p><em>Image credits: Getty Images</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

"Good luck!": Pink stops show as pregnant fan goes into labour

<p>It's not every day that you can say pop icon Pink stopped her show as you were going into labour, but for one Sydney fan this was her reality. </p> <p>The <em>So What </em>singer briefly stopped her show after spotting a pregnant woman getting wheeled out of her concert by a medic on Friday. </p> <p>Wanting to know what all the commotion was about, Pink stopped half way through her performance of <em>Our Song </em>and excitedly tried to find out the baby-to-be's gender, after discovering  that the concertgoer was experiencing contractions. </p> <p>"Is it Alicia or Alex being born?" she asked from the stage, referencing her birth name, Alecia Beth Moore. </p> <p>The singer then playfully said that they shouldn't "be looking" anymore and urged the crowd to give the woman some "privacy."</p> <p> </p> <div class="embed" style="box-sizing: inherit; margin: 0px; padding: 0px; border: 0px; font-size: 16px; vertical-align: baseline; outline: none !important;"><iframe class="embedly-embed" style="box-sizing: inherit; margin: 0px; padding: 0px; border: 0px; font-size: 16px; vertical-align: baseline; outline: none !important; width: 573px; max-width: 100%;" title="tiktok embed" src="https://cdn.embedly.com/widgets/media.html?src=https%3A%2F%2Fwww.tiktok.com%2Fembed%2Fv2%2F7333559856185593090&amp;display_name=tiktok&amp;url=https%3A%2F%2Fwww.tiktok.com%2F%40miss_chantal%2Fvideo%2F7333559856185593090&amp;image=https%3A%2F%2Fp16-sign-sg.tiktokcdn.com%2Fobj%2Ftos-alisg-p-0037%2F22874a6d4d174a149b284ecb5a642be4_1707477473%3Fx-expires%3D1707865200%26x-signature%3DNsu2Nw7zUT%252Bf6ndURt3fjSjaZfg%253D&amp;key=59e3ae3acaa649a5a98672932445e203&amp;type=text%2Fhtml&amp;schema=tiktok" width="340" height="700" frameborder="0" scrolling="no" allowfullscreen="allowfullscreen"></iframe></div> <p>"Wow, Our Song, that was the one that did it.

I don't even know what to say. But we have to sing now. Good luck! It's gonna be great! You're gonna do great," she said. </p> <p>A clip of the moment was shared on TikTok, with fans hoping that the mum had a safe delivery.</p> <p>"Baby is like nah I wanna see pink I don’t wanna just hear. Hope mama had a safe delivery 💕💕" one wrote. </p> <p>"Yep or maybe bubba is thinking will this make pink my godmother 😂💕" another added. </p> <p><em>Images: TikTok</em></p> <p> </p>

Should you be worried about the amount of coffee or tea you drink?

<p>Before you reach for that cup of coffee or tea, have you ever thought about whether that caffeinated beverage is <a href="https://cosmosmagazine.com/health/body-and-mind/debunks-vices-coffee-caffeine/">good or bad for you</a>?</p> <p><iframe title="Vices: Is coffee good or bad for you?" src="https://omny.fm/shows/debunks/vices-is-coffee-good-or-bad-for-you/embed?style=Cover" width="100%" height="180" frameborder="0"></iframe></p> <p>Most of us will drink coffee or tea each day.</p> <p>It helps keep us alert, especially in a world of the nine-to-five grind. Some workers rely on caffeine to get them through shift work and night shifts.</p> <p>Many, like me, would just collapse in a heap if it weren’t for that liquid black gold to keep us peppy in the morning.</p> <h2 class="wp-block-heading">What is caffeine?</h2> <p>To get a better picture of how coffee or tea affects us, let’s examine the active ingredient: <a href="https://cosmosmagazine.com/podcast/huh-science-explained-stirring-the-science-of-caffeine/">caffeine</a>.</p> <p>Caffeine is a <a href="https://www.betterhealth.vic.gov.au/health/healthyliving/caffeine" target="_blank" rel="noopener">drug</a>. It’s a white, odourless substance known to chemists as 1,3,7-trimethylxanthine and is made up of 8 carbon, 10 hydrogen, 4 nitrogen and 2 oxygen atoms.</p> <p>Caffeine occurs naturally in coffee beans, cocoa beans, kola nuts, and tea leaves.</p> <p>It is an adenosine antagonist, blocking the A1, A2A, and A2B receptors in the brain and body to promote wakefulness. Normally, adenosine (a chemical compound with a similar 3D structure to caffeine) binds to its receptors, slowing neural activity and making you sleepy.</p> <p>When caffeine, instead, binds to the receptors, adenosine is blocked and brain activity speeds up, making you feel more alert.</p> <h2 class="wp-block-heading">History lesson</h2> <p>Tea and coffee are the most common way for humans to get their caffeine fix.</p> <p>Drinks made using coffee beans date back more than a thousand years to the coffee forests of the horn of Africa.</p> <p>Legend says that, around 800 CE, an Ethiopian goat herder named Kaldi noticed his goats were energetic and didn’t sleep when they ate the coffee beans. Coffee then spread eastward to the Arabian Peninsula, reaching Yemen in the 15th century, and Egypt, Syria, Persia and Turkey in the 1500s. From their it made it to Europe and eventually the whole world.</p> <p>But caffeine is also present in other beverages like tea, cola and even some foods like chocolate.</p> <h2 class="wp-block-heading">Is it bad for you?</h2> <p>Given how prevalent the drug is, are there negative side effects we should be worried about?</p> <p>For one thing, it is an addictive substance. And the more you drink, the more you need.</p> <p>“Our body tends to adjust to a new level of consumption,” Kitty Pham, a PhD candidate at the University of South Australia and expert in nutritional and genetic epidemiology, tells <em>Cosmos</em>. “Your body does develop a tolerance to the caffeine. So, you start to need to drink more and more to feel the same effect as before.”</p> <p>Caffeine can also act as an anxiogenic – a substance that can trigger heightened levels of anxiety.</p> <p>Pham notes some risks associated with too much caffeine consumption over a long period of time.</p> <p>“Greater than 6 cups per day, we did see an increase in dementia risk,” she notes. “There’s also some research on how it might increase your cholesterol. There’s a substance in coffee called cafestol that can regulate your blood cholesterol. If you’re drinking too much coffee, it might be increasing your cholesterol. So, there are risks, but often they are at really high consumption.”</p> <h2 class="wp-block-heading">What’s the limit?</h2> <p>So, how much caffeine is too much according to science?</p> <p>“That’s, the million-dollar question, isn’t it?” Pham laughs. “There’s a lot of varying research on it. It’s hard to tell a definite limit. But generally, most studies really agree that one to two cups of coffee, or an equivalent of 100 to 200 milligrams of caffeine is safe and okay.”</p> <p>The average cup of coffee has about 100 mg of caffeine. On average, instant coffee with one teaspoon of powder contains about 70 mg of caffeine, while a coffee pod has 60–90 mg.</p> <p>Other drinks containing might have even more caffeine, making it important to monitor your consumption more carefully.</p> <p>A 355 mL can of Red Bull energy drink has more than 110 mg of caffeine. Meanwhile, an average bar of dark chocolate has about 70 mg of caffeine.</p> <p>Many people are moving away from coffee to drinks like tea and matcha which may have <a href="https://cosmosmagazine.com/health/flavonoids-black-tea/">additional</a> <a href="https://cosmosmagazine.com/health/tea-drinkers-may-well-live-longer/">health</a> <a href="https://cosmosmagazine.com/health/black-tea-mortality-risk/">benefits</a>. A 100-gram cup of black tea has only about 20 mg of caffeine, while matcha can have 140–170 mg of caffeine!</p> <p>“Looking at the US, they usually recommend less than 400 milligrams. So overall, moderation and keeping your consumption to one to two cups – that’s what I’d recommend.”</p> <p>Now that I’ve written about caffeine, I think I need another cuppa. It’s only my second of the day, I swear. </p> <p><em>Image credits: Getty Images </em></p> <div> <h3><em><a href="https://link.cosmosmagazine.com/JQ4R"><noscript data-spai="1"><img decoding="async" class="alignleft size-full wp-image-198773" src="https://cdn.shortpixel.ai/spai/ret_img/cosmosmagazine.com/wp-content/uploads/2023/04/Apple-Podcasts.svg" data-spai-egr="1" alt="Subscribe to our podcasts" width="300" height="54" title="should you be worried about the amount of coffee or tea you drink? 2"></noscript></a><a href="https://link.cosmosmagazine.com/JQ4U"><noscript data-spai="1"><img decoding="async" class="alignleft size-full wp-image-198773" src="https://cdn.shortpixel.ai/spai/ret_img/cosmosmagazine.com/wp-content/uploads/2023/04/Spotify.svg" data-spai-egr="1" alt="Subscribe to our podcasts" width="300" height="54" title="should you be worried about the amount of coffee or tea you drink? 3"></noscript></a></em></h3> </div> <p><em><!-- Start of tracking content syndication.
